yes its something you could have done at home. its just a matter of plugging the 2 USB sticks into your USB port. the hard part is getting a hold of those 2 USB drives. NHTSA gives detailed pdf instructions (including a company and a phone number that lets you purchase these drives...but why would anyone do that?).

the rogue pdf is RCRIT-19V654-9996
incidentally the problem was the backup cameras made after May 2018 would remember and keep using user settings...even if you set it to where you cant see anything. So the update will ignore your backup camera settings and restore them to default when you put it in Reverse. i havent tried it.
