For anything with more than one socket, you just plug in a second cable into a free socket, once the phases are synced up unplug the extension cord or cut the socket free.
For singular sockets straight into the wall, unscrew, clip on connectors with a V shaped knife and same as above.
Although when I was working we usually would take images onsite before even considering moving the devices.
It's definitely not bullet proof but I've set up my laptop to lock when Ethernet or the monitor is unplugged or any new USB device is plugged in.
This stops most but not all live imaging.
Work laptop came with an M.2 SSD and had a sata connector as well.
Due to size both wouldn't fit buy you can fix it using an mSata disk and an adapter.

It's easy now to keep work and private separate since I need to shutdown one to boot in the other.
The disk in encrypted so my data is safe if they would ever take the laptop back without asking. But pulling out a disk is going to be way faster then copying or erasing.
Also, just put a limit on requests per IP? https://nginx.org/en/docs/http/ngx_http_limit_req_module.htm...
