All my Hack's with that problem, I solved it with this
Note: use gfxutil to check your HDEF = PciRoot(xxx)/Pci(xxxx,xxx)
My is PciRoot(0x0)/Pci(0x1f,0x3)

If you don't need HDMI audio output, yes, you can use the official 1.4.3 release + the following setup(only example). You need to change both Pci(0x1b,0x0) and alc-layout-id 1 to something for your motherboard.

Code:
    <key>Devices</key>
    <dict>
        <key>Audio</key>
        <dict>
            <key>Inject</key>
            <string>No</string>
        </dict>
        <key>Properties</key>
        <dict>
            <key>PciRoot(0x0)/Pci(0x1b,0x0)</key>
            <dict>
                <key>alc-layout-id</key>
                <integer>1</integer>
                <key>No-hda-gfx</key>
                <data>AAAAAAAAAAA=</data>
            </dict>
        </dict>
    </dict>

We have the same build. Would you mind sharing your EFI Folder?

Thank you for your assistance. I am still having issues with my hack.

To give you some background. My hack was working fine on Mojave 10.14.6. I saw others having success on 10.15.2 so I decided to give it a try (which I regret now). I did a clean install.

Once I got macOS install I was unable to boot from my main drive so currently I boot from the USB. After using your EFI the issue still remain.

I will click on the macOS drive on the clover screen then it will take me to a blank screen and stay there.

Do you have any advice?
 
@kjc : My EFI folder is extremely boring. I use a fresh Clover install without any adjustments to the config, then add FakeSMC, Lilu, Whatevergreen and IntelMausiEthernet. Done.
 
use -v on boot and take picture of the screen

I waited for 10 minutes to see what will happen. Nothing showed up except for these dots.
