This would surprise me - can you link to this discussion?
You should be able to rsync from an Arch mirror, and then use whatever method for the EnOS mirror (there’s not a huge amount in there so you probably don’t need to do anything particularly special).
Looking at your other threads, this may be of interest: https://repo.m2x.dev/ (discussion here: Current, Daily, Weekly, Deferred mirror setup - #7 by ricklinux). If all else fails I can probably enable rsync for that.
