Windows 10: Disable drives like "G" via GPO?

Moin, I'm currently building a Citrix Farm with virtual machines (Windows 10 for the clients and Windows Server 2016 for the servers) running on terminal servers, now I don't want the users connecting to the Citrix Farm to see any drives.
By default it is possible to disable or hide the drives via GPO, but you can't hide all drives there, only from A-D (I think).
Now to my problem I still have drives like E and G, how can I hide them? It is possible to hide the drives locally with regedit, but that is not the whole point.

With kind regards

:)

Drive G

This is one of the known issues with the update as Recovery partition should be hidden and is accidentally assigned a drive letter.

Right-click Start>Command Prompt(admin)

Type in the following:

diskpart

list volume

select volume 3

Replace 3 with the number of the volume which is assigned a drive letter. (In hundreds of MBs)

remove letter="G"

Replace G with the Recovery drive letter.

Don't worry, removing a drive letter would not cause any harm to your device.
