How to use php 8?

I´m using the YNH App Hubzilla for quid some time. Even so the git YNH App Hubzilla repro is not updated lately there is a way to update the App by the command line, which worked fine in the past. The new update requires PHP 8 - i think the YNH App Hubzilla is set up to use PHP 7,3 How can I change this? How can I tell the YNH App Hubzilla to use PHP 8? Thanks for help!
