Hackintosh with CSM?

Hi everyone, I have a HD 7730 from MSI and Dortania's guide said it can run Monterey. But its VBIOS doesn't support UEFI so I have to enable CSM. And the guide said it should be disabled. So how do I install Monterey with this GPU?

Flash a compatible VBIOS?

​

Thank you!

UEFI is not checked
