Set up vpn on rPi that can work with windows built in vpn

I have a work laptop that won’t let me install any software so I can’t install a WireGuard client. Currently I have WireGuard set up on my raspberrypi at home. But obviously can’t connect to this on my work windows laptop. How can I launch a vpn on my raspberry pi that I can use with the built in windows vpn software?

I use SoftEther VPN for this purpose. Since it supports L2TP/IPsec, you can connect to VPN using the built-in function of Windows.

Can I deploy this along with my current pivpn instance ? I can follow commands but wouldn’t know how to do anything without a guide so want to confirm I don’t mess up my current set up.

I’m running SoftEther with WireGuard on a single Pi, so it can probably coexist with PiVPN as well. I’ve never used PiVPN before, though, so I’m not sure how to actually do it.
