Satechi have said they are doing a base. I had one when I had my M1 Mac Mini, it's a really nice solution. It holds an external SSD so give you a very nice way to add fast storage.

Be aware its only 10Gbs, (USB 3 speeds) not TB4/5, so its possible that the SSD you use will be throttled by the connection...
OP is coming from a fusion drive so it'll seem like voodoo how much faster it is.
