I had the opposite problem on a 2016 Mustang with HID lamps, Europeans got fobbed of with lower power HID units to avoid the need to fit headlamp washers. The lights were rubbish, worse than my previous on Halogen lamps.
 
Since I worked some magic on the rear sequential turn signals I looked at the matrix headlights for fun. Here are the differences between the matrix headlights and the US reflector headlights.

-Green = Same signal as US reflector headlights
-Yellow = Must add headlight leveling sensor/MCU (6 wire module)
-Blue = Easy to add signal
-Pink - Intelligent front lighting system (5 wires module, although does connect to CAN so it would be interesting to see how it reacts when connected to a car without it stock).

I'm not going to actually attack this project as I don't want to spend the money. Although if someone were to send me a pair of headlights I'll see what I can do, no promises. If I get it to work I'll send you everything needed back and document the process on here, if it doesn't I'll just send the headlights back and document why it didn't work on here.

It's totally possible that the majority of the extra wires would not be needed for basic operation. I don't know how the headlights would react without the intelligent front lighting system or leveling sensor, but basic high and low beams may work fine. Sequential turn signals and DRLs would work fine.

As I did with the sequential rear turn signals, the goal would be to have everything plug and play with custom harnesses.

The auto-levelling system might be difficult as you'll need a sensor in the rear suspension for the car to estimate "squat" and adjust the headlights down accordingly. At least that's my understanding of how auto-levelling headlights work.

That's the MCU I mentioned above.
 
I'm moving everything over from the other thread as this one makes more sense to the topic. This will be the main thread for North America Reflector to Matrix headlamp conversion
 
Because I like a challenge... here are the part numbers of everything presumably required to accomplish this.

Left Headlamp (Korean market): 92101-CV100
Right Headlamp (Korean market): 92102-CV100

Below not required for basic functionality (just normal high/low beams)
AHLS ECU: 92190-CV000
IFS ECU: 92170-CV000
 
More info found today after digging around on my car...

The male connector and terminals on the headlamp housing are removable, the connector just twists out. So... if I cannot source the connectors, I could remove the terminals out of the US headlamp and transfer the connector over to the EU headlamp. The terminal part numbers between the US and EU headlamps are the same for the given signals. There are unused terminals on the US connector, not enough for auto leveling or IFS, but enough to get sequential turn signals working. You would just have to be very careful when re-pinning the EU headlamp.

This is still theoretical because I'm not sure how the EU headlamps would operate without leveling or IFS connected.
 
Here is a theoretical wiring diagram if you wanted the entire system to work. There would also be programming involved to enable IFS and AHLS. I did find the headlamp connectors in Korea, and found a cheap headlamp to test on, so within a month or two we should know if this actually works, and to what degree of install it requires (just headlamps vs headlamps/AHLS/IFS modules together). As of now I am planning on installing the IFS module under the drivers seat because it's easier than taking apart the dash to put it behind the AVNT.

Parts wise this is what is required to complete this project. This gives you full stock like install of Matrix Projectors with IFS and AHLS with the wiring digram I posted. Additional custom PCB would be needed for sequential turn lamps (same PCB I sell with my rear turn signal harness).

Programming is required. See the video below. I used a Launch x431 Pro Elite programmer, others models may work.

AHLS ECU: (Parameter Setting and Zero Position Initial).
IFS ECU: ("Parameter Download")
Front View Camera (FVC): ("Variant Coding", Body Type: GT, HBA Option: None)

 
Got my first headlamp in... SEE EDIT BELOW. I also have the IFS ECU on its way now, so I'll continue testing. Low beams, high beams, turns (sequential and non-sequential), parking, and DRLs work perfectly fine just sitting on my desk without being hooked up to the vehicle. The low beam only draws 1.3 amps which is crazy. High beams draw 3.2 amps, with a total of 4.5 amps for both.

EDIT: High beams work without IFS. I was assuming that they are different circuits (so I was powering either one or the other). They must both be energized at the same time. Going over the wiring diagram of the leveling system, I noticed that only the low beam was tied into it, and the AHLS tech info states "AHLS only operates with the headlamps on". So I powered both. High beams work!

With this testing done. It is totally feasible to retrofit the matrix projectors with sequential turn lamps on a North American EV6. This is what's needed to make it work:
-Headlamps (duh)
-Headlamp connectors x2 (HERE, I used Korgou.com to purchase them and forward the package to the US).

I currently cannot source the male North American Headlamp connector. Which means an "intercept harness" of sorts isn't probable. BUT, the North American 14 pin connector and overseas 20 pin connector share the same terminals. While annoying, it is certainly feasible to "de-pin" the North American connector and insert those terminals into the overseas 20 pin connector. This satisfies my goal of not hacking up the wiring on my EV6. Without any extra work, you would get matrix projectors in the very basic sort. Adding one wire to the 20 pin connector gets you sequential turn lamps. Adding 5 wires to the 20 pin connector (plus adding the IFS ECU and AHLS ECU) would get the full system working, with the exception to figuring out what programming is essential to getting everything to work together. What I am building for my EV6 is a single harness that in one install adds IFS/AHLS. Not quite plug and play as I had hoped (due to issues sourcing that male connector that would make this project SIMPLE), but also not impossible. Bumper must be removed to replace the lights. I am still attempting to source the connector... see below. If anyone can help find this, it would take the install time down significantly. With that connector it would be 100% plug and play, with the exception of programming and 2 wire taps... one for VSS (speed) behind the cluster, and one on K-LINE at the OBDII connector.

@kyle11111 Have you found a P/N for the IFS module or what all hardware is required for it? The US cars don't have the IFS camera up behind the rearview mirror so I'm wondering what else is missing.

US market (borrowed from TechincallJeff's video), that space is blanked out:
