UDM-Pro, PFsense, IPSec VTI

Just a quick sanity check?

I am running PFSense Pro, my friend has a new UDM-Pro. We are wanting to set up a IPSec VTI. The only info I can see on google/YT is at least a year old and most being 3+ years old.

Can it be done? Is it more of a pain to do? I know we can do it manually, but with many VLans on each side, setting up the P2’s on my side, and not knowing how it is set up on the other side yet, it is making me want to see if it is worth going down this rabbit hole, wondering if all the time spent is wasted on a dead end.

Does the UDM-Pro still want a remote IP, or will a FQDN work now?
