If you're concerned about that do not give internet to your tv and use any kind of tv box instead (shield tv, apple tv, etc).
with things like amazon's sidewalk you might not have any choice https://en.wikipedia.org/wiki/Amazon_Sidewalk
How long until they have built in cellular or use a mesh?
So that TV box can phone home instead of your smart TV? What's the point?
I wouldn't use Apple TV, Shield or other proprietary black boxes if you want a private setup. Linux on a mini-PC with Plasma Bigscreen, your own over-the-air antenna for local TV, VacuumTube for YT, and the high seas for other content.
