I haven’t had this happen personally, but are you allowed to edit your hosts file? I’m assuming those IP addresses are coming from DNS resolution, and if you hardcode those DNS entries to resolve to 127.0.0.1, it’ll stop the ads.
nslookup <ip address>
should give you the domain names, if not there’s DNS logs in Event Viewer that should tell you.
From a cursory examination, it looks like there are at least some models where you can disconnect the antenna, for which you may get a warning you can just ignore. Seems a lot easier than a faraday cage. But a lot worse than a car not outfitted with that kind of tech.
