Fix flickering/glitchy screen on Intel UHD 630 Graphics without config.plist

[qash20888]

So after a week of trying I have been able to install MacOS High Sierra on my new components. The parts list is as follows:
MB: MSI Z370A-Pro
CPU: Intel Core i3-8350K
RAM: 16 GB Ripjaws 2133 MHz
SSD: Silicon Power 256 GB
GPU: None

After the installation, there was no wifi as my card did not work OOB. I was able to fix that. Yay! Now I have graphics problem and the solutions on the internet suggest that I alter my config.plist file but the problem is that I do not see the EFI partition at all. I tried Clover configurator, EFI Mounter V2, V3. I even tried adding directory through terminal. There is no EFI partition on my SSD. So is there a way to fix the issue without having to do something with the EFI partition (or config.plist)?

All help will be appreciated.. Thanks!

You should read the rules, in particular the one regarding profiles.

I just noticed that my SSD has APFS Volume instead of Mac OS Extended (Journaled). Is this a bad thing? Did I screw up the installation?

macOS High Sierra includes a new file system APFS. If your system drive is solid state, the installer will convert from HFS+J to APFS in both a fresh install scenario and an update scenario.

"Now I have graphics problem"
What specifically is the problem ?
