Ryzen 5 5600 CPU Sapphire RX 6600 instalation nightmare

I've followed the dortania guide excessively which resulted in having no display output after booting the installer. I've looked around in fixes and playing around with my boot-args but all of it led to still no display output. Afterwards, I tried using other peoples EFIs and changing the SMBIOS to MacPro7,1 and one of them which is the only one that booted leads to this almost screen broken like display (Image of it: https://imgur.com/a/nApxTxN also the box you see is a movable cursor ). I know my GPU is not broken or something and people say/ I've also seen the RX 6600 works with Monterey which is what I'm currently trying to install (Ventura and Sonoma which I've also tried have the same results). My PC Specs are:

Motherboard: Gigabyte A320M-H
CPU: AMD ryzen 5600
GPU: Sapphire Pulse RX 6600
RAM: Corsair Vengeance LPX 16GB DDR4 3600MHz

Please help me keep my sanity
