Desktop video 11.4

Hi,
I am using blackmagic intensity pro 4k and trying to install desktop video setuyp in my rhel 8.1. But the drivers fail to build. I saw in release notes that desktop video supports rhel 6-7 only . Is there a way around to install it on rhel 8.1 ? Or when can we expect the new desktop video software to be released which supports rhel 8.1 .

Here are the logs -

[root@localhost x86_64]# rpm -ivh desktopvideo-* mediaexpress-3.6a13.x86_64.rpm
