Yes, as long as you do not break the two loops at the same time.

Put the new enclosure on the rack, with at least one disk drive inside. Plug the cables on the power supplies. Open one loop and insert this new enclosure on the loop. Check on Command View that it's discovered.

Open the other loop and insert this new enclosure.
