In which ini file and how to setup default vr.PixelDensity?

Hi, I’m new here and would like to set vr.PixelDensity for Meta Quest (Android mode). Now I know it should work, but I have no idea where the value belongs. According to the “XR Best Practices” documentation, it should be in the “Config/DefaultEngine.ini file under SystemSettings”. But there is no “SystemSettings” section. Please help.

UE 5.3.2., plugin Meta XR 1.91.0

Edit: This is Bing answer:
" According to my research 123, the vr.PixelDensity variable should be placed in the [SystemSettings] section of the DefaultEngine.ini file. If this section is missing in the file, you can add it at the end of the file. The vr.PixelDensity variable should not be anywhere else in the file, because that could cause conflicts or invalid values. I hope that answers your question. :blush:"

Edit: Not working.
