A:Answer No, unlike ASUS who wants to insist just because it has USB-C to Displayport that the Rift S will work, it does not.
I recently purchased this laptop, as well as a USB-C to DisplayPort adapter verified by many to work with the Rift S, and I can confirm it does not work, even on a fresh install. Nothing in the BIOS fixed it; no updates or drivers fixed it; the Rift S (as well as the Rift CV1 if you're curious) does NOT work on this laptop.
By the way, ASUS I am extremely disappointed you would blindly suggest it works with your laptop without actually testing to see if it does.
