GoKawiilGuide details how to remove ads from Android TV using third-party apps
A tech writer published a setup guide for replacing Google TV's ad-laden interface with Projectivy Launcher, swapping YouTube for the ad-free SmartTube client, using Wholphin for Jellyfin, and remapping the remote with Button Mapper. The configuration was tested on two Chromecast with Google TV devices and a Hisense TV, and the author says it should work on most Android TV hardware.
