Acer Predator X27P and Gsync

I have two Acer Predator X27P that support Gsync Ultimate; they are both connected through DP.

The problem is that the drivers don’t recognize them as supporting Gsync:

I am using Nvidia drivers 465.31, KDE 5.21.5, and kernel 5.11.20 (but the problem existed on all the past versions of all 3).

For the moment I am using the workaround of enabling “Allow G-SYNC on monitor validated as G-Sync compatible”, but it is annoying (as I have to re-enable it every time I boot).

Best regards.
