Find the cellular and/or wifi antennae and cut them.

this does not work.

I have a tesla wall charger. I never wanted to connect it to wifi, but it creates its own unique wifi access point TelsaWallConnector-blah-blah.

so I thought - I'll just disconnect the antenna!

nope, still shows up.

so... I'll just wire the antenna it to a dummy load!

nope, still shows up.

It appears the wifi chipset has an on-board antenna and an external antenna connector and it uses them both.

I suspect this stuff happens for wifi and cellular chips in lots of devices.

It works depending on the manufacturer. Honda places the TPU in the dash behind the head unit. Use some spudgers and you can disconnect and remove the TPU. Takes 15 minutes at most.

I was referring to cutting the antenna wires.
