I have a storage pool on my Windows 11 system that is configured like this. tiered storage pool

I want to remove one of the physical disks from this pool.

From the UI, it seems I can only Extend the pool size.

From Powershell, I tried resize-virtualdisk -FriendlyName "TieredDisk" -Size (607GB), but got this error:

resize-virtualdisk : Not Supported

Extended information:
The Windows Storage Provider does not support shrinking virtual disks.

I wonder if I forgot to install some system tools. If MS does not support resizing a virtual disk, why do they provide this command?
