HI! help me virtualize plz? gpu passtrough and qubes os

so i've joined the forums just to say that i suck at pcie/pci passtrough :stuck_out_tongue: ... i want to use qubes os with some kind of snapshotting/ auto backup (because i always somehow crash the qubes os, so i want to be able to restore a backup). so that's why i installed freenas, but turns out i can't gpu passtrough using freenas (at least i don't know how). so i thought i'd get some help from the level1 pro's. what would you guys recommend me? i want a windows 10 machine with the gpu on one monitor and a qubes os machine on the other and i don't know how i'd do that. and sorry for my bad explaining, english isn't my native language
