Skylake cannot boot Ventura installer. Pls read the full question.

I used a prebuilt EFI for my ThinkPad T470 which comes in Skylake and Kabylake CPU. I use the Kabylake EFI and booted Ventura but when I use my Skylake EFI (I built by myself) it will get stuck at the Apple logo or gives the prohibited sign( sign fixed by changing SMBIOS). I was wondering if it needs an iGPU patch (spoof to kabylake) to boot?
