[ovirt-users] 4.3 -> 4.4 upgrade question

Hello! We have only one 4.3 cluster and try to upgrade it to 4.4. I believe that engine-setup change the Cluster Setting "Default Network Provider" to "ovirt-provider-ovn" during upgrade procedure. So then we add freshly reinstalled RH8 host back to this cluster the oVirt tries to configure OVN on that host. But we don't want to use OVN. Is it safe to change this setting back to "No Default Provider" and continue hosts upgrade process ? Thank you.
