My Book Duo in RAID 1 - is WD software necessary?

can anyone help me with the question:

is the official WD software necessary for the RAID 1 to be working?

I’m on the latest macos and I have it once configured as RAID 1 under the WD utilities, but later I decided to uninstall it because (as repeated here more times in various topics) it seems like the WD software prevents macos from waking the external disk up. without WD utilities instead, it works just fine.
now, without WD software is the RAID working on on my disk or not?
