How do I check the TV in store does not have modem with esim? Or at least detect and disable embedded cell modems at home?
The average person willingly connects them to their wifi, why would TV makers go through the effort and expense? Maybe I'm being too optimistic though...
Bluetooth is enough, theoretically, if they have an agreement with Amazon: https://en.wikipedia.org/wiki/Amazon_Sidewalk
And most TVs these days have Bluetooth.
ATSC 3.0 also specifies a dedicated long-range return channel with a range of many kilometers.
