People have mentioned you can ssh into it, so it might be possible to make changes to the /etc/hosts file.

That's assuming the device doesn't use straight IP addresses for whatever it's communicating with. That's possible, but pretty unlikely.

Or update/modify the networking, WiFi, routing, gateway, firewall, or other configurations on the device itself such that it connects to and communicates over only specified networks and/or hosts.

Again my point is that relying on off-device, local-netork hardware and configs is brittle.
