Most things can be changed in the Configure menu (such as speed, plugging, BSOC, etc.,) but things that are safety related such as height limiting, side gate switches, entry sensors and such are usually protected by a passkey. The passkey that raymond will issue the dealer tech will have all of this information in a code string, deleting the entry sensor option and this will have to be downloaded to the truck via laptop. If it is indeed in the configure menu you'll more than likely have to have a dealer tech come out anyway unless whoever you purchased it from defaulted the password/superwords back to 1 and 2 (which I doubt).
