[Help] z390-I aorus wont post with CSM disabled

Hardware:

i7 9700k

Z390-I aorus pro wifi

XFX RX 580 4GB

Guide I followed: https://github.com/vpoola88/gigabyte-z390-i-aorus-pro-wifi-hackintosh

The issue I'm having is despite following and almost having identical hardware as the user in the linked guide, when I select the same bios settings as him all I get is a black screen. Not even the ability to boot back into my bios. I was able to boot back into my bios by resetting the cmos and narrowed the culprit to "disabling csm" in my bios settings. Because disabling csm causes my mobo not to post, I left it enabled contrary to the guide resulting in the following error: https://ibb.co/pKfdvb5

Any suggestions/help would be greatly appreciated as the whole point of me building this mini-itx box was for a hackintosh lol. Thanks
