How do you create an Azure VM with an Ultra Disk

I'm trying to create an Azure VM (specifically a D8s_v3) with an "ultra disk" as the system disk. It's one of the choices in the dropdown for system disk, and my configuration passes the final validation check, but when I press "create" it fails with the error message:

  UltraSSD_LRS sku is only supported for empty disks.

An "ultra disk" doesn't appear to be a choice for an added disk.

(This is in the Azure Portal, in case that matters.)

How do you include an "ultra disk" in an Azure VM?
