i7 8700 + Asus PRIME Z390M-PLUS + iGPU installation hangs at blank screen after verbose boot

Hello,

Been trying to install Catalina 10.15.5 for a couple days on my desktop now. Configured the EFI folder by following the OpenCore vanilla desktop guide. Followed the Coffee Lake and z390 sections as well.

How I created the installation media:

I created the USB installer from my MacBook with createinstallmedia.

Guide I followed:

OpenCore vanilla desktop guide

Relevant computer specs:

i7 8700 Coffee Lake

Asus Prime z390m-plus

Nvidia RTX2070 (Disabled)

SSD Corsair MP510

Problem: I can boot the USB stick, select Install Catalina, see the Apple logo and a progress bar moving, but then I get a blank screen. The computer is still on and seems to reboot gracefully as I press the physical restart button. My motherboard has HDMI and DVI and neither works.

BIOS configuration:

Went through all settings mentioned in the guide that I could find. CFG-lock is disabled, fast boot is disabled, 4G is enabled, and so on.

Relevant folders and files:

Here is the EFI folder in the USB stick:

And here goes my config.plist:

I removed all framebuffer-conX-enable and framebuffer-conX-alldata entries, but I spent a lot of time trying to get these right as well.

Sanity check link (not sure if this is persistent):

And the OpenCore logs:

At this point, I don't know what else I could try. Any suggestions, please?

Thank you very much.
