If you can get your hands on a service remote it will allow you to access a menu to disable that and a bunch more (a lot of the OLED burnin prevention features you can’t normally fully disable)
Huawei and Xiaomi phones have IR blasters as well. I always try to buy phones that have those, because A) "i lost the remote" and B) "shut off every TV at the store" is hilarious.
The first device i had that had this was a Palm, and it wasn't like "here's a remote control" it was "this 1 button will cycle every known TV IR code for the power button." Someone eventually released an actual IR blaster app for Palms, though.
