How to stop calendar integrations all together - I don't want any calendars

[zabatha]

I see lots of folks writing about the default calendar issues tied into zoom. Up until recently, I never had a calendar integration issues. Then suddenly it started to open Outlook and the only solutions I see is to choose another default calendar. Is there a way to stop it wanting to integrate with any calendars at all? I'm not interested in calendar integration. Would appreciate anyone's advice on this.
