Installation of Ventura, How bad mistake?

10500H notebook with Intel UHD GFX and Rtx 3060 mobile.

I used opencore efi for my processor variant and have made it as far as installing MacOS Ventura as we speak with 18mins remaining.

What I didn't do upon re-eatching install guide on yt is clear nvram and then choose the boot option opencore which appears after the clear. I'm simply installing from the Install MACOS menu option, I've formatted a separate partition into apfs successfully using diskutil at recovery of macos.

1. How bad have I done I'd here.
2. Will all the correct flags n drivers install still, or will I have some ops to do post install?
3. I edited the configuration plist with new serial number for imac 1,1 when the original plist stated macbook pro as per video tutorial, will this matter?.
4. Is there a way for macos to utilise the rtx 3060 in laptop or will it simply drive purely from the uhd graphics?

My whole reasoning for embarking on this quest is due to wanting to play 2 apple arcade games that I didn't want to purchase an apple device for as I run android, will this be capable?

Kind regards.
