[Xen-API] XCP: How to change PCIe slot for first display?

I am experimenting with GPU passthrough, and so I have two GPUs installed on my server.

My PCIe 2.0 x16_1 slot operates in x16.  And my PCIe 2.0 x16_2 operates at x4.

Since PCIe 2.0 x16_1 operates at x16 mode, I want to pass it and its faster GPU through to a guest.  Problem is, by default, when XCP boots, the GPU in the PCIe 2.0 x16_1 (x16) slot displays first.  And so, my faster GPU displays xsconsole, which of course doesn't need much speed.

QUESTION:  Is there some way to configure XCP so that xsconsole will be displayed by the GPU in PCIe 2.0 x16_2, which would leave the PCIe 2.0 x16_1 open for GPU passthrough?

Thanks much for any help provided!

Best regards,

P.S.  I know that some motherboards allow for selecting with PCIe slot will display first.  Unfortunately, mine doesn't allow for such configuration.
