Can I synchronize multiple calendars independently?

[kallekruse]

Use case: I would like to sync two calendars:

1. My personal calendar, between my Ubuntu laptop and my Android phone. This already works using Radicale-DecSync, DecSyncCC and SyncThing (kudos!)
2. A shared calendar, between my laptop and multiple Android phones, maybe also another Ubuntu laptop.

I would like to share these two calendars independently: I would not want to give all devices who will have access to the shared calendar also access to my personal calendar. Is this doable with Radicale-DecSync, DecSyncCC and SyncThing?
