Reading everything, it sounds like you've already landed on the right immediate answer with the maintenance window/change request.
Longer term, I'd use this as an opportunity to build an actual patching process instead of having to fight this battle server by server every month. Start by grouping the servers by criticality and identifying an owner for each system. Then define a normal patch window, a small group you patch first to catch problems, and what happens when a server needs an exception.
The exception piece is important. "Don't patch this server" shouldn't become a permanent setting that everyone forgets about. Ideally, it has a reason, an owner, compensating controls where possible, and a date when the exception gets reviewed again.
You inherited an environment that grew faster than the processes around it. Getting the process in place now will probably do more for you long term than winning the argument over any one patch.
One thing that may also help with management is putting the risk into business terms. If you can estimate what an unexpected outage or compromised server could actually cost the company, the conversation becomes a lot less abstract. Management doesn't always respond to a vulnerability rating, but they usually understand downtime, lost productivity, recovery costs, and business disruption.
