UHD 630 No 4K on Dell Optiplex 3070 MFF i5-8400T 32GB RAM

The display I am using is a DIY 15.6 inch 3840x2160 display. MacOS Ventura now sees it as a 1440p display in System Settings. Besides resolution, the rest related to display work, including acceleration.

Please assume that DVMT cannot be modified from BIOS. The official firmware has no DVMT control. For some reason I can hardly extract my bios so please avoid UEFI shell fix if possible.

Attached with my EFI. I guess I only have to work on config.plist. Thanks for the help.
