I have an older Sony TV which has (what I can only guess to be) Google’s Android TV app installed on it. I’m sick of getting new recommendations from Amazon and Disney+ and all those services. Is there a way to strip it down bare bones and get everything I need from another app repo - kinda like with Graphene vs Android?
Basically, the only way is to disconnect the TV and use it as a dumb screen. Lineageos supports a few set top boxes (see here).
