Game runs at 72Hz on Quest 3

Not really a bug I guess, but I got the game on Quest 3 rather than SteamVR for the lower latency and Mixed Reality mode... And I was really disappointed to see that it runs at 72Hz with apparently no option to change this. This is not only a lot less smooth than 90fps or 120fps, but the 72Hz display creates a very annoying and headache inducing flickering effect for people who are sensitive to it. Would it be possible to get a 90Hz mode, even if it means having less detailed environments and visual effects ? Thanks !
