I'm not sure where to post this so I'll start here.
I am completely new to the Raspberry Pi and Raspbian Linux (any Linux for that matter). I want to create an RPi that will be completely disconnected from a network and without the possibility of someone accidentally turning on networking. I would like to completely remove the TCP/IP stack as well as any other networking stack and remove the wireless connectivity. I would also like to make it so that only certain devices can be plugged into the USB ports and be recognized. I'm working on an RPi 3B
Any help or guidance would be greatly appreciated.
