I encountered this when setting up a Time Machine volume for my wife. In samba shares you can set that value in smb.conf by adding

  fruit:model=ModelX,Y

MacOS will accept plenty of device names that perhaps don't make sense for file servers (I have mine set to Watch6,18), but it makes sense realizing that Bonjour is used for a lot more than just network volumes.

Wow. Last time I did that, it was still AFP shares. Time Machine wouldn't recognize anything else.
