Problems getting igpu working

My core specs: i7 6700k rx 5600xt z170 pro gaming sonoma 14.0 Imac 19,1 smbios

The dgpu is working but the igpu doesn show up in system information. It's skylake so I needed to spoof it's id. I need the igpu for additional display outs.

some config.plist values I have set: device id: 12590000 APPL,ig-platform-id: 00001259 frambuffer-patch-enable: 01000000

boot-args: -v keepsyms=1 alcid=1 agdpmod=pikera unfairvga=1

entire config: https://pastebin.com/zkQQ4STR
