Play along - create a PinePhone keyboard

Would it be possible to move bigger versions of the dip switches into that space? It would be great if it were possible to turn modem, cameras and WiFi on and off without disassembling the phone.

I doubt, unless someone designs a mechanical arm which converts these movements.
The basic idea of those switches was to disable parts in a hardware way.

You may put switches to that place but it will only able to do it using a software way, so practically it is not possible.
