Help - Can't get to the installer

Hi there people,

Been trying to get OS Ventura installed on my:

Gigabyte Z790 GAMING X AX
Core i5 13600K
ASRock AMD Radeon RX 6800 XT


for days now and no matter what I try, I can't get to the installer.

In my BIOS settings, I set all as listed in the OpenCore Install Guide with the exception of:

Intel SGX (not in my bios settings).
VT-x (not in my bios settings)
Execute Disable Bit (not in my bios settings)

and strangely enough SATA Mode to set AHCI, I can't find anywhere either...
