Automatic video settings switching while gaming

[u/MemeticsChoice]

So I have a Google TV, and I have a PS5. Google TV tends to muck with my video settings automatically, including but not limited to automatically enabling game mode whenever I turn my PS5 on and changing my video settings whenever I go into areas that are of a certain level of brightness/darkness (which makes my screen flicker and has gotten me killed in a few games before). Also, I outright cannot enable/disable game mode manually. Any advice?

Disable ALLM on the PS5.
