Wireguard VPN in VenusOS

I found out that since VenusOS 3.20 there is support for Wireguard in the kernel. Specifically, the changelog says: - Add wireguard-tools as optional package (opkg) as well as enable the wireguard driver in the kernel.

Has anyone managed to get this working yet? Neither opkg list nor opkg list-installed shows anything about wireguard and opkg install writes error - read only filesystem.

Try GitHub - kwindrem/TailscaleGX: tailscale for Victron Energy GX devices

Tailscale uses Wireguard.
