Help - SMBios MacBookPro13,3 i7 6820HQ ZBook15G3 Big Sur- how to get HDMI out working?

• tested under Windows: HDMI output connected to iGPU
• dGPU (Quadro M2000M) disabled via SSDT
• with the SMBios MacBookPro13,2 the HDMI output works: Catalina, Big Sur
• with the SMBios MacBookPro13,3:
  - Catalina: Adjustment of the kext AppleGraphicsControl.kext under /System/Library/Extensions/ makes HDMI output work
  - Big Sur: Adjustment of the AppleGraphicsControl.kext under SLE causes a bootloop https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/extended/post-issues.html#writing-to-the-macos-system-partition

My questions to you:

1. can I use SMBios MacBookPro13,2 for my cpu without hesitation and without system performance suffering?

2. is there any trick how to get HDMI output working with SMBios MacBookPro13,3 under Big Sur otherwise?

Best thanks for your help!
