Yes, I have two graphic cards: one is MB embedded, and one - nvidia.

You said:
"The first one that u use for FreeBSD as host OS and the secondary,that' an
Nvidia card,that you want to pass thru"

No.
I use nvidia everywhere. Its PCE address is 59:0:0.
In my /etc/X11/xorg.conf I have the line : BusID "PCI:59:0:0"
All is good here - graphic cards configuration doesn't matter.

I have two usb pci controllers:
xhci2@pci0:134:0:0: class=0x0c0330 rev=0x03 hdr=0x00 vendor=0x1912
device=0x0014
subvendor=0x1912 subdevice=0x0014
vendor = 'Renesas Technology Corp.'
device = 'uPD720201 USB 3.0 Host Controller'
class = serial bus
subclass = USB
xhci3@pci0:216:0:0: class=0x0c0330 rev=0x03 hdr=0x00 vendor=0x1912
device=0x0014
subvendor=0x1912 subdevice=0x0014
vendor = 'Renesas Technology Corp.'
device = 'uPD720201 USB 3.0 Host Controller'
class = serial bus
subclass = USB

One of it I passed thru to VM-1, and other - in VM-2.
