Is it possible to change iCal export link?

Is it possible to change a default iCal export link?  I know I can use custom iCal links and that is not applicable, looking specifically to change the iCal default link. 

Thanks! 

No, this is not possible.  Can you explain your use case for why you'd want to do this?

Separating from long term property manager and no longer want them to have access to the calendar.  I understand it’s semi public by viewing on listing sites but I’d like the details to be unavailable via the cleaning software they use, etc  

Anyone who has been provided the iCal link indefinitely has access until if/when they decide to delete it from their system?

Yes, that is correct.  The design thinking is that, as you point out, that data is publicly visible on your website and listing channels anyway, it is not a secret, so is not a privacy concern.  And since you might likely be using the same iCal feeds in any number of places, for example listing channels, allowing you to change or disable them would open up a whole host of problems best avoided.
