Can you do a cumulative update in SQL server failover?

When does SQL Server fail over to an upgraded node?

If there is an unexpected failover, the upgraded nodes do not participate in the failover until Windows Server failover cluster role ownership is moved to an upgraded node by setup. By default, SQL Server setup automatically determines when to fail over to an upgraded node.
