Last time I had to remove a host - I didn't have your issues. Yet, I'm not claiming the opposite - just that in case the host is also a gluster node , oVirt will intentionally prevent removal of the node. Your approach could be absolutely valid in case there is no Gluster involved - yet for HCI , Gluster brick has to be replaced prior taking any actions for the removal.
