I believe the tech that is not allowed in the US is something that literally dims sections of the lights that would shine line into the eyes of an oncoming driver. This is different than the auto dimming lights feature in US cars that just shuts off the high beams when an oncoming car is detected. Most of the tech is made by a company called Gentex. If you have an auto dimming rear view mirror in your car they most likely made it.
My MDX does it, and they have had that capability since at least 2017.
