Currently there is no resolution and is expected behaviour.
Workaround:
Ensure the DRS Automation level is set to manual before starting the patching or upgrade process. For NSX upgrades via EAM, one possible workaround is to limit the number of hosts that can be put into MM by using the EAM option.
Procedure
- Browse to a cluster in the vSphere Client.

Note: Do not disable DRS.
When DRS is disabled, the cluster’s resource pool hierarchy and affinity rules are not reestablished when DRS is turned back on. If you disable DRS, the resource pools are removed from the cluster.
