Does hyper-v support crossfire technology?

Question

Hyper-V

the point is the following. there is a hyper-v server based on windows 2016.
the server has a regular Radeon R7 370 gaming video card installed, which is quietly shared into virtual machines and everything is fine. But for some time (with an increase in the number of VMs), the brakes of the interface inside the VM became noticeable, the investigation revealed that the GPU is constantly loaded by 90-90%
. So, you need to increase the performance of the video subsystem.
The cheapest option is to buy another video card.
the question is, does hyper-v support two graphics cards?
Do I need to combine them into crossfire, that is, buy exactly the same video card, or can I put different ones?
