I am a little confused but the features seem to be there even if I do
not recall how to test :

titan# uname -apKU
FreeBSD titan 15.0-CURRENT FreeBSD 15.0-CURRENT #0 
main-n276246-628d1501f7ec: Fri Apr  4 06:57:29 GMT 2025

Create a new ZPool and then a ZFS filesystem with xattr=on :

titan# camcontrol devlist
