Don't want to awake this topic again but did you guy check the Settings/Car/Exterior Lighting/Comfort Area?
My software version is 11/2019.55 and it I remember (sorry can't reach out to the car now to double check) but some comfort access settings especially the Welcome Carpet settings has some more items now. It allows you to have it on when unlocking the car or turn this feature off or turn the carpet lightning on when you turn of the engine and open the door in night.
while i am going to check it physically later, here is a video that show that menu.
