Activating Windows 10 Virtual Desktop

How do you activate Windows 10 VDA on Citrix XenDeskop in customers own datacenter infrastrcutre?

Currently, my environment consists of virtual hosts and we are leveraging Citrix XenDesktop with Windows 7 for user desktops. The desktops are currently activated via a KMS Server.

We are looking to upgrade our Windows 7 Image to  Windows 10 Enterprise (Brand new Image build, not an in-pace upgrade) and obtain the licensing via the Office 365 Subscription for $10 per user per month to activate windows 10. 

What are my options to activate the Windows 10 Virtual Desktops so no user interaction is required? Can the Windows 10 Desktop still be activated via KMS?
