I don't know if it's helpful, but we are running a CentOS7 machine that has 
CAVE on it, and 
everything works well.

I believe we are running an NVIDIA driver for the NVIDIA chip. I don't know if 
maybe the version
is slightly different than what you're running, but here's the output from our 
machine, if it's
helpful to your IT at all, from running `lspci -k | grep -3 'VGA'

83:00.0 VGA compatible controller: NVIDIA Corporation GK208B [GeForce GT 710] 
(rev a1)
        Subsystem: Micro-Star International Co., Ltd. [MSI] Device 8c93
        Kernel driver in use: nvidia
        Kernel modules: nouveau, nvidia_drm, nvidia

I hope they're able to figure out the driver issues, because then all of your 
machines should
work well with CAVE.

Best of luck!
