The Dynamic quorum is related Windows Cluster, so I will help you add the "windows-server-clustering" to this thread.

As far as I know, the function of Dynamic quorum is making sure node could up when there only exists one node, so I think you could reset up any number of nodes on the DR site. Suggest at least two Exchange nodes and one witness node.

About Exchange site switchovers, Microsoft suggest deploying three sites, two for Exchange member and another for witness server, you could have a look about this article: Datacenter switchovers
