If you are talking about the rear seat reminder chime (and notification on the instrument cluster), I don’t believe that can be defeated with Carista or the scanner of your choice.
I hate that damn thing- 80% of the time I am driving the Land Cruiser solo- no child, no pet, no valuables left in the rear seat so I don’t need a reminder to check the rear seat. With that said. you just know there is someone out there who is willing to sue the auto manufacturer because they left a toddler unattended in a car seat and the vehicle didn’t advise them to check before parking and going into the casino for eleven hours
