Using proton VPN on a raspberry pi?

Hello everyone,

I was wondering if anyone here knows if it's possible to set up Proton VPN with CLI on my Raspberry Pi 3B which is running raspbian OS (no graphical interface).

Essentially I have a server, which I access with tailscales sometimes in case that could cause any interference (it doesn't with the other computers), and I want it to connect to a specific ProtonVPN server with P2P at all times. Is there a way for me to do this? On the official website there isn't much info on whether that is possible or not.

Thanks in advance

EDIT: Would OpenVPN work?
