First and foremost, I'd like to congratulate you on your successful installation. I can comment on your problem because I was in the same situation when I was attempting to install Big Sur, but it was my fault because I was attempting to install on a spinning drive, but I simply swapped to an SSD and everything was fine.

Thank you for your help, I have two installation one on ssd and other on spine drive both drivers working fine.

I found Kext from wannabe hacker,   https://www.insanelymac.com/forum/topic/356679-guide-installing-ventura-1331-on-legacy-775-asus-p5q-e-intel-q9650-geforce-gt-710/

 

NoAVXFSCompressionTypeZlib-AVXpel.kext 

 

telemetrap.kext 

FakeSMC.kext  preferred over VirtualSMC for legacy systems.  Also provides for better monitoring

and add on CryptexFixup.kext
