Based off of https://forum.qubes-os.org/t/wireguard-vpn-setup/19141
To clone VPN for another location, clone sys-vpn-location Qube to a new Qube
Go into this new Qube terminal and show the current VPN connection UUID
nmcli connection show
Delete the initial vpn UUID
nmcli connection delete <UUID>
Then import your new location vpn.conf file and run import.
nmcli connection import type wireguard file vpn.conf
Don't forget to cat vpn.conf for the new endpoint and reconfigure the firewall rule to that new endpoint IP
These all autostart when using, so close them out on each new one, and when you select the location VPN, it will all automatically work. Download a bunch of .conf files from provider into a personal Qube that can copy 1 by 1 into each new cloned VPN Qube.
