[REQUEST] PCI IRQ Routing Table in AMIBCP

Hello,
I’m trying to manually assign an IRQ to a specific device with editing in AMIBCP the PCI IRQ without having any success or understanding of what I’m editing. I read some pages of ebooks but I couldn’t find anything about the editing with AMIBCP.
How does that PCI Table works? Is it possible to assign an IRQ with that table?

Any help is really appreciated.

Motherboard : z390 master aorus
Bios : F11e

anyone that knows something about it?
