This is a tricky one as the Menu entry varies based on the favorite title. If your favorites never change, you could change the favorites shortcuts in macOS system settings -> Keyboard -> Shortcuts -> App Shortcuts as Orion is a native application. However, macOS requires that the menu command is matched so you might want to rename some of your favorites to have shorter titles.
Another workaround is to move all favorites into folders so there are no favorites to occupy those shortcuts. I understand this isn't an ideal solution either.
