Some TVs do not give you that option though. Shield or not, I have one that will straight up block 90% of the screen every 10 minutes if it doesn't have a connection.

I would toss it, but it was 250$ and 65" with a decent display. So I used ssh to get into it and install a firewall to block 90% of the TV from access, including the update service. Also have filtering through my network firewall for ad servers, update servers etc.

So now the scan for a connection works, but they aren't getting much of anything in terms of metrics or telemetry or other information from the TV. I also disabled the default launcher and installed a different one on it as well as jellyfin.

I will never buy another TV like that though, it was an absolute pain to get it working. It should be illegal to hinder usage of a TV just because they are being blocked from invading your privacy.
