Apologies for the late reply!
The bus-id in CPU-Z is, unfortunately, not the ID we're looking for. Based on MSI Z390 Gaming Edge motherboard, HDMI is on Port 0x05 at Bus ID 0x01. Therefore please try this configuration:
Index 1: BusID 0x01, Type HDMI
Index 2: BusID 0x00, Type DUMMY
Index 3: BusID 0x00, Type DUMMY
Index -1: BusID 0x00, Type DUMMY
If you are unsure how to enter this, just upload your config.plist and I can make the change.
Are you running High Sierra with Nvidia Web Drivers for the GTX 1060? Or are you running Mojave, but without any accelerated graphics driver for the Nvidia card?
The real device ID for your IGPU is 0x3E98, but this is not supported by MacOS so we have to fake it to either 0x3E9B or 0x3E92. With this ID, MacOS will use the accelerated graphics driver, but that driver thinks that all of your IGPU video ports are DisplayPort. But with the framebuffer connector patch above, we can fix this problem and get HDMI working.
As mentioned above, please try the configuration shown. If you need help, just upload your config.plist. Also ensure that Lilu and WhateverGreen are installed (both of them must be installed). For security reasons, you should remove Serial Numbers from SMBIOS section of config.plist before you upload.
