RAID 1 Mirrored Disks on Monterey?

Do the LaCie terminal command instructions still work? Will it work for Monterey OS on a 2020 M1 Mac mini to mirror a pair of WD elements 6 TB 3.5” external HDDs connected to the USB-C ports? Will Time Machine recognize these and successfully back up to them?

Mac mini 2018 or later
