If the device (TV) in question is doing sketchy things like sniffing for open wireless networks, I don’t think pointing it manually at a zero-access WAP stub is going to stop it - it’ll probably just dump that connection and look for another one that works.
So what would you suggest as a countermeasure? In theory rendering the on-board wifi inoperable would work, but this requires an actual alteration to the device and some technical knowledge on how to do so without damaging the TV itself.
Edit: in addition to privacy issues, this sort of behavior would be an actual cybersecurity risk.
