But just want to confirm if it supports MSCS with shared storage including quorum?

Failover clustering is supported on AHV by enabling MPIO on Guest OS Windows Server level.Leveraging MPIO enables the Guest to completely takeover the control for ability to determine which failover peer should write on the shared vDisk. Following documentation lists out the steps to leverage Volume Group from Nutanix Cluster to be presented to the VMs for configuring In-Guest clustering.
