Currently, there is no option to change the migration encryption option for the HE VM [1] Please make this field editable. [1] Falls with "There was an attempt to change Hosted Engine VM values that are locked."
May not be the best idea for performance reasons. But I don' see why it needs to be blocked, it should work...
Verified with: - ovirt-engine-4.4.1.7-0.3.el8ev.noarch Verification steps: 1. Edit HE-VM 'Host > Enable migration encryption > Encrypt'
