to Onireves1 - As for RPI, you can easily view from the configuration whether you disable Wi-fi and bluetooth - sudo raspi-config. Joshua, one of four WiFi modes available in NodeMCU is "off" . According to its documentation, it seems to have a WiFiManager. Wonder if you may have tried that to see if you may disable it..
In general, team "must" prove wi-fi is disabled. Thus, if there is absolutely no way you can disable it. I am afraid that this won't be allowed. I'll have to further discuss this with the TC. Not sire if we should mandate a network scanning to target any traffic from the your NIC connection. However, first step, please see if you may disable it via the WiFiManager.
