Need help with NetworkManager, VPN and IPv6 (lemm.ee)

I was setting up my laptop for traveling and adding Wireguard VPN configuration.

The Wireguard config generated by router only contains IPv4 address (10.0.5.x), and while testing the VPN to my surprise "what is my ip" websites can find my IPv6 address (I USB tethered mobile connection to my laptop).

It looks like NetworkManager does nothing about IPv6 connection if VPN doesn't have IPv6 settings, which is bad for road warrior type of VPN configuration.

Is there an easy toggle to turn of IPv6 if VPN is connected and otherwise? Or is only option to disable all IPv6 no matter what?

Hmm, how about we have public facing IPv6 to gateway and then NAT to IPv4 internally. I wouldn't have a problem with it then. In general I wouldn't even have a problem with IPv6 or v8 or whatever even internally as long as we'll always have NAT.
