If you already have a "smart TV" of some kind, one strategy is to block it from having Internet access at your router and then use an Android TV based streaming box/stick or other external source for all content (OTA tuner, 4K Blu-Ray player, game console, etc). It's pretty easy to side load apps like Kodi and SmartTube on Android TV (a YouTube client with ad blocking, other features and zillion UX improvements).
