The version I’m specifically using is Adhuard Home, which runs on a raspberry pi that sits between your home network and the internet. Basically just like Pi Hole. So it will filter the DNS queries on your devices, including smart TV.
One of the options for a blocklist was specifically labeled as Smart TVs, so I’m presuming that one would take the fuss out of watching the logs and choosing which requests to block. This list is likely available for pi hole too, so that feature wouldn’t be unique. I know sometimes these will also block firmware updates, so that’s something to watch for.

We use silicon bags and magnets. You let the top of the bag drape over the side of the bucket(tub? basin?) and hold it in place with a few magnets. From what I can tell the results are the same for the steaks and meat we cook and none of the sketchiness from eating slow heated plastic.
