OptiPlex 5090 MFF i5-10500T UHD630 no-video/black screen

Last two days I have a problem with UHD630, can't get video output with IGPU acceleration enabled.

Only can get video output with VESA driver (i.e. no GPU acceleration).

WEG patched IGPU device with a recommended values

Framebuffer

When booting in verbose mode "-v" and after kext loaded I get signal lost.

DVMT Pre-allocated set to 64MB and Total memory is MAX

I also have Optiplex 5060 MFF i5-8500T (UHD630) and everything is OK, but not with this box.
