For those with more capable routers, local dns adblocking, or NextDNS; you can add a static DNS entry for "androidtvwatsonfe-pa.googleapis.com" and direct that to 127.0.0.1, you will also get no ads on the stock launcher. At least on Android 11 (For the Nvidia Shield). You might have to restart the device or empty the cache for it to take effect.
