for surface-mount antennae (which cant be used for 5g or 5ghz wifi) you would just brush the same metallic fingernail polish on the trace :)
I've bought smart TVs, not connected them to WiFi, and that was the end of it.
You can hear whispers about all kinds of sneaky things like refusing to work, but some of the best TVs out right now are LG smart TVs that will function completely identically to a dumb TV if you don't connect them to the internet.
Here's the thing: At the end of the day, a smart TV has capabilities that I don't need or want, including to change how it functions without warning or consent. However unlikely the possibility is, a smart TV still has the capability to connect to an open network, phone home, and start doing shit I don't want, which means I have to trust it to not do that.
On the other hand, my old dumb TV has none of those capabilities, so I can trust it precisely because I don't need to trust it. I know it can't do anything except display what it receives on its inputs.
Therefore, any time I've considered replacing my TV with a newer one, I've always weighed predictability against uncertainty and opted in favor of the predictability of what I own.
Maybe that's overly paranoid of me, but at the end of the day, I just haven't wanted a new TV as much as I've wanted something I can trust.

So any 2 bit hacker wannabe in an apartment complex? I mean if I was a teenager in the wifi days I would have been playing games like that.
Or buy an older used TV
Why should I destroy my property?
Why Isn't, for exanple, using my property to spy on me a criminal offense?
