Showing black screen on Catalina usb installer on HP Z440

[Mttk]

Hello friends, I need help fixing the boot issue from Catalina USB installer. Working on HP Z440 with E5-2670 v3 Processor and 16GB Ram with Quadro K2000 with nvme drive using PCIe expansion card. I'm stuck at this point where the system just about the load the installer UI. It says unsupported processor and went to black screen. I have waited long but it shows nothing after that. Anyone please help, really appreciate.

Serial ports (SuperIO) should be disabled in the BIOS settings.

use -cdfon in boot argument and copy lilu.kext and whatevergreen.txt in your EFI/BOOT/KEXT/Other folder
