Multi GPU in Opencore

Hardware:

CPU: i5-10600k

GPU: 2x AMD R5 340X (aka R7 250X)

RAM: Nemix 2x8gb DDR4 2400 (Samsung chips, defaults to 2667)

Motherboard model: Gigabyte H470M DS3H

Screen(s) Number: 1 currently (4 total)

Screen(s) Resolution: 1920x1080 x 4

Audio Codec: intelmausi

Ethernet Card: intel gbe

Wifi/BT Card: (if available) N/A

What guide/tool I followed: https://dortania.github.io/

What part I got an issue with: The above system is actually running perfectly right now. I did not get the iGPU working quite right, but the motherboard doesn't allow simultaneous iGPU/dGPU so, no worries. I have the above mentioned R5 340X GPUs and I currently have 1 of them installed. As the R5 340X is simply the Dell version of the R7 250 it must be renamed to the R7 250X to work. I already patched it, created the SSDT, all fine... but...
How do I add the 2nd GPU? I would assume that I have to install it, boot linux, check the port, get the acpi... but then once I have that... do I just create a 2nd entry in the current SSDT or do I create a 2nd SSDT?

What files/config I am using: https://pastebin.com/8E9m39pX

Extra Info: I only shared the SSDT as everything is running fine.

Thanks
