Host start and used 5th videacard

[Fullmoon]

good day. I have 6 video cards on my host. and I want the host to use a specific video card, for example, the fifth one. now he uses the first videocard. tell me how to do it, please
there is no point in rearranging the cards. since I exactly need the first port for the GPU passtrought, and 5th Port pci-e x1 for host
for example now:

I think this might help:

Do that for every card that you don't want to use as output. Maybe it'll work. Got no experience with it.

Usually i have a BIOS option for primary GPU.
