DNS Adblocking although you’ll need special rules for your tv (each vendor varies) and it has limitations. The ad networks have known about dns Adblocking as long as it’s existed so they circumvent it. On a pc with something like ublock (especially the old manifest 3 version) you can also stop scripts used to get around this but obviously on tv that’s not an option (plus it doesn’t always work, cat and mouse game)

I’d really like the ad industry to burn and everyone who works in it to go to jail
