2022 F350, I'm an avid hunter and it drives me nuts when I open my doors and the truck lights up like a carnival ride on the exterior..
There has to be a way to turn this feature off..

Dealers don't seem to have much interest in helping with this..

Anyone ??

 

It could be because there is no way to control individual courtesy lighting. There is a good chance a lighting control module is involved and not exactly known if you can obtain selective lighting. The dealership may be aware of this.
You might consider trying another dealership.
