Help using external VPN services with Mistborn

Hi,

Got mistborn configured on a VM running in my homelab. I would like to set up mistborn in a way so that my etire network is on the wireguard vpn.

While reading through the documentation I didnt see any sections for adding third-party vpn configurations. Is there a way to import my surfshark vpn configuration into mistborn?

Ideally, I would like to set this up so I have 1 - 2 diffrent vpn configs that point at diffrent countries / locations. Then configure these to be on my router.

Please let me know if this is possible.
