ovmf

I'm using RHEL 7.3. From what I understand, RHEL supports ovmf in qemu, but I am unable to install any package related to ovmf. I know it is still a technology preview, but I still can't install it, even with the beta subscriptions enabled. Can anyone give me some directions on how to get ovmf working for UEFI in qemu? I know it is there because of these links:
