I set ig-platform-id=0x12345678 then I successfuly reboot without selected inject efi strings, but I need still cpus=1.
In about my Mac it is displayed my card name correctly but ram still 7mb,



then
I follow your this step:
sudo touch /System/Library/Extensions && sudo kextcache -u /

IOKitWaitQuiet() timed out.

after that, I edit again like this ig-platform-id=0x191B0000

then I reboot,
"please read the my next post"

The panic image indicates DVMT-prealloc is set incorrectly.
If you can't set it, you must use the minStolenSize patch.
It is covered in the guide:
https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

I can boot only with cpus=1 now.
finally it is enabled my graphic cards, but something wrong before login screen is like this after 5 seconds it goes to normal:



after login, if I click Launcpad, icons coming is very slow, looks like no graphics acceleration enabled.

cpus=1 requirement is a separate issue from graphics.
Open a separate thread.

For any graphics problem in this thread, you must provide data as per FAQ, "Problem Reporting".

In the future, please provide only EFI/Clover (as per "Problem Reporting"), not the entire EFI folder.
Your ioreg indicates you're not booting with Intel injection.
Note: You should not have NoDefaultProperties=true... it causes FakeID to not work.
