Hide Mark ticket as closed

We have many use-cases where the “Mark ticket as closed” button that a requester can use has come back to us in negative ways. Specifically around Major Incidents. We have a process for Major Incidents that require specific teams to review, analyze, and communicate and when requesters go in to Mark a ticket as closed, they are able to do it even if our required criteria isn’t met. 

It would be great to be able to either find ways to hide that button based on ticket type, or allow for that button to follow the same business rules that our Agents have to follow.
