Not a good approach.
It's important to know if the node was also a gluster peer in the storage pool - if yes, it needs to be replaced with 'replace-brick' or 'reset-brick' (depending if you use the old hostname or not).
Once the storage node is replaced - oVirt will allow you to remove it.

Last time I had to do this I removed from the database.

(at your own risk)
On ovirt engine switch to the postgres user from root:

su - postgres

Enable postgres 10 and connect to the engine database:

. scl_source enable rh-postgresql10
psql -d engine

Change <host name to remove> to the name (Name column of the host in the UI) of the host you want to get rid of ( leave the '\' and \'' in place )

BEGIN;\set host '\'<host name to remove>\''DELETE FROM vds_dynamic WHERE vds_id IN (SELECT vds_id FROM vds_static WHERE vds_name = :host);DELETE FROM vds_statistics WHERE vds_id IN (SELECT vds_id FROM vds_static WHERE vds_name = :host);DELETE FROM vds_static WHERE vds_name = :host;COMMIT;
<CTRL d - exit>
