Dibbling Microsoft AutoUpdate - macOS

I have a customer with a Mac mini M4 with multiple user accounts.  Each user has an access to Office 365 apps, Outlook, Excel and Word.

The issue I am having is with Microsoft AutoUpdate.  I have turned off  "Automatically keep Microsoft apps up to date" on all of the users.  This has not stopped update application from opening and showing on each of the users there are updates available.  If one of the users tries to run the update while an application is open by another user, it cause all kinds of problems.

My questions is, "Is there another way to prevent AutoUpdate from indicating there are updates available?

Thanks
