Call for help

Hi once again…,…
Even though I have used linux several times through the years, managed to accomplish difficult (lets say) tasks, this damn thing with the gpu (I also need the controller upon which my ssd for the VM is on) passthrough I cant do it no matter what, Its a cursed task and all guides forget to mention something or something else happens and no one knows to answer. Being trying that for almost a month reading for several things and following 3 guides (2 of them in here). I am frustrated to the point of punching the screen. SO, any good samaritan has the will to help via team viewer to set this damn thing up and see what causing the problem is more than welcome.

Thank you in advance
