Finally getting around to switching to OC. Could you explain the difference in these bios files?

Do I need to worry about the ones from Elias64Fr? My Z390 isn't flashed with custom TB firmware.

In BIOS F9j, Gigabyte included a patched microcode for the Intel CPU that addresses a couple of security vulnerabilities. Elias extracted this new microcode and surgically implanted it into our F9i BIOS.

If you choose to install the modified BIOS, you must first install the OFFICIAL F9i BIOS. Failure to do so will brick the motherboard.

It is also okay to stick with the unmodified F9i BIOS.

Thank you! One more question for now (I was just editing my original post but saw your reply).

It looks like HackinDROM doesn't work with Mojave. Do you recommend going to manual route to switch to OC and then update OS to use HackinDROM?

It says it works on 10.15 and above, but I'm on 10.14.6 of course.

Also:
  • File on left is for Broadcom WiFi/BT (4.5 MB).
  • File on right is for Intel WiFi/BT (51 MB).
Which one do I need?

EDIT: Did some more reading, I think I need the Broadcom one since I'm not using the onboard intel wifi card :).

Yes; switching manually to OpenCore is recommended if you're on Mojave. This will provide a lot of good lessons that will come in handy later. Create the OpenCore configuration in the EFI partition of a USB flash drive and test it that way (press F12 at Gigabyte splash screen and select USB disk from BIOS Boot Menu). Confirm that it can boot Mojave. Please follow the Clover to OpenCore Transition Guide.

Also:
  • File on left is for Broadcom WiFi/BT (4.5 MB).
  • File on right is for Intel WiFi/BT (51 MB).
Which one do I need?
  • If you have a Broadcom WiFi/BT card such as Fenvi FV-T919, use the file on left.
    • This one is recommended.
  • If you're using the on-board Intel CNVi WiFi/BT module, use the file on right.
    • Use only if you understand the limitations of the current OpenIntelWireless project.

Thanks, yup that's exactly what I'm following. However, I'm a little confused at the end portion:

I can't seem to find where the 4 steps are described. The new link (Update 21 SEP 2021) in that guide just has info on HackinDROM. Is there something I'm missing?

EDIT: The manual OC download file has two Plists: config-AMD-GPU and config-Intel-iGPU. Which one am I supposed to edit?

Please see the section How to Use in the post below. Although it is from a much older version of OpenCore, the general principles are the same.

Ah brilliant, thank you. The link already has an answer to my "edit" question. Will let you know if I run into any issues :).

@CaseySJ Appreciate your help. I'm currently typing this from OC 0.70 :D. Everything worked out great with the guide steps, including trying it out on a USB stick first.

What do you recommend I do next? My plan was to update to big sur now using software update like you mentioned in a previous post. You also mentioned:
  • However, some older third-party audio kernel extensions (kexts) can cause boot problems in Big Sur. If in doubt, simply post a screenshot of /Library/Extensions before starting Big Sur installation.
Here's a screenshot of my extensions folder. Let me know if it looks okay:
