Good evening, @AMZ ...

Unfortunately, I do not think that this is possible with Calendar feeds from Canvas (just one "s", by the way).  I looked through the following Guide, and I didn't see anything about being able to do this.  How do I view the Calendar iCal feed to subscribe ... - Canvas Community  Back in 2016, this was also confirmed by @Stef_retired: Solved: Single course calendar feed - Canvas Community.  And unfortunately, I'm not sure that anything new has been developed since then.

Sorry that I don't have better news for you, but I hope this has helped to answer your question.  Take care, stay safe, and be well.
