Five years from now, 5G will be widely deployed, with a connection density of 1M/sqkm, 1000 times larger than 4G. The TV will connect directly to the 5G network without asking for permission. For your convenience [TM].
Or somebody will invent a small short-range backhaul-less 5G spoof microcell you can put next to the TV that will confuse the TV's modem into connecting to nothing.
Or just wrap the TV in a Faraday cage. But keeping the screen visible might make that tricky.
There's always been rumours that some Intel vPro CPUs have modems (and entire secondary CPUs..) built in to the chip itself.
Atom x3/x5/x7 processors have a modem in the CPU package.
I imagine disabling the modem without breaking the TV would be impossible.
