Do you have IOMMU enabled in your bios settings?
Sometimes we need to simplify:
1. See Step 6. BIOS/Firmware parameters setup by @CaseySJ for Z690 ProArt Creator - Golden Builds
2. Create a new USB drive with latest Monterey 12.6 OS - download using gibMacOS from Github
3. Remove any other internal/external drives not required for the Monterey install
4. Check your EFI folder using ocvalidate (OCAT) and fix all errors
5. Select the USB drive from the Boot Menu (F8) link in BIOS EZ Mode - to be sure you boot the correct UEFI drive.
