Prevent reminders being added for particular calendars

Is your feature request related to a problem? Please describe.

We're using shared calendars for group-wide things like when payday is, or who's in the office. Some caldav clients (e.g., MacOSX calendar) add reminders to those events automatically if they do not already have a reminder attached.

Ideally, reminders should be per-person, not per-event but that doesn't seem possible (so Fred wants a reminder when Joe is in the office; but Alice doesn't want one and shouldn't be spammed --- if she wants to know she can look at the calendar).

Describe the solution you'd like

So what I'd like to be able to do is turn off reminders for a calendar. So when caldav clients try to add one, it's discarded.

Describe alternatives you've considered

-- Removing ability for people to sync two-way to their on-device or on-laptop or other-cloud calendars. This forces update via the web interface, which does not add a default reminder. (This removes much of the advantage of having a nextcloud calendar) -- Training all our staff to remove the 'add alarm' feature in their calendar apps. (this is hard because there are lots of different apps out there that are doing it, and less tech-savvy users are going to have difficulty)
