I ripped the wifi / onstar and gps antennas out of my 2020 Chevy Bolt the day after I bought it. Took me a couple of hours since the access was awful, but that's one time pain. No issues since, and I have a phone I use to drive the head unit so there was no need for those antennas to even exist.
I tried this once.
I got a tesla home charger and it had a unnecessary wifi AP that kept showing up in my house. So I figured, I would stop this.
Opened it up, and disconnected the wifi antenna mmcx connector.
Nope, seemed when unplugged, it would switch to an onboard antenna for the wifi module.
so I reconnected a dummy load antenna to the wifi module.
and it still used the onboard antenna.
at that point, I gave up.
I think there might have been a possibility of downgrading the firmware to an older version that could disable wifi, but I didn't try to find it.
I believe this kind of thing happens with onboard cellular, wifi and bt. They are more resilient to degraded or disconnected antennas than you think.
