i7-9700k iGPU boot issue - OC 0.6.5

OpenCore 0.6.5

CPU: i7-9700k
GPU: iGPU (UHD 630)
RAM: Corsair Vengeance LPX 3200 2x16GB
Motherboard: ASRock z390m Pro4
BIOS revision: P4.3

Following the Dortania guide - mix of Mac and Linux - to get a bootable USB installer. I compiled *.aml files in Linux on the (empty) PC I'm trying to install on, and copied the files over to the Mac I used to make the install USB.

Boots in verbose fine and it seems like JUST at the point it would trigger the UI install, the monitor shuts off. I don't just mean goes black, but loses all input connection.

I can't figure out how to proceed. I've tried HDMI and VGA monitor connections, and played around with a couple config changes for the framebuffer and no dice. Any insight? Thanks.

Config and OpenCore text file generated are linked below.
