I have this working on OPNsense 25.7.1_1-amd64. There were bugs in prior versions and I was unable to make it work. I would give it a go. If you are still having problems, let me know and I'll try to assist.
I am running 2 Tunnels and BGP. 1 tunnel is preferred with lower metric (100 vs 200). Failover works and happy with my setup.
