Hi,
In simple terms AVD is the front end for your Virtual Desktop, so each session host will have the same behavior as the Windows operating system.
That is, those hosts can be attached to your AD DS, and you can apply GPOs and all the policies of an AD DS to them.
If the Session Hosts cannot be attached to an AD DS, then you can create installation scripts on each host or apply additional settings through Intune.
I hope this helps!
