Forwarding video card in mac (parallels)?

Question

macOS

There is a hackintosh, today I changed the video card to a GT 640. Now there is a 560Ti nearby, I planned to insert it into a home server (it’s a pity to sell it, but there’s nowhere else) and then I remembered that on Habré they talked a couple of times about video forwarding. But everything was in Linux.
Will it be possible to use a second video card in virtual machines on my hackintosh? There is a slot for a second video card.
And are there many difficulties with the setting? I just don’t feel a special need for a separate video card for virtual machines (I have Windows and Ubuntu there, they run very simple applications), but I want to try it. :)

I myself was interested in a similar question. As far as I understand, it's not possible on a Mac. There seems to be no KVM kernel module and no way to redirect PCI. But I saw articles that it is possible to transfer a card under Linux to a hackintosh. And in theory, if you create 2 virtual machines, then you can work with ubuntu, Windows and poppy, in theory, without rebooting. Moreover, XEN, as far as I remember, under Linux gives a very high speed.
