WVD Golden image

Hi,

We have been playing around with WVD for the last few weeks, and have been happy with equivalent to RDSH servers.

From what i understand, it should be possible to create a "golden image", that is used to spawn VM, which is stored on an ephemeral disk. 

https://getnerdio.com/academy/how-to-speed-up-windows-virtual-desktop-with-ephemeral-os-disks-and-saving-on-storage-costs-too/

But i cant seem to find any Microsoft articles on, how to deploy WVD with ephemeral disks natively in WVD - do i have to use Nerdio or some other 3. party tool for this?

PS: We are using FSLogix, and are aware that the VM state + all written data, is lost when the VM is shutdown / rebooted.

Thank in advance.
