Drobo 5c M1 Big Sur 11.1

Has anyone attempted to attached a 5c to an M1 Mac mini running Big Sur 11.1 with the USB 3.0 cable (not 3c to 3c but 3c to usb 3) without installing Dashboard?
Does M1 see the Drobo as a usb drive?
Do you startup the Drobo unattached and then connect to the Mac?
What steps do you take to shut down the Drobo without Dashboard?
Do you just eject the drive per the Mac Finder?

Thanks in advance for your replies.
