I'm not sure why you need kernel-lt. NVIDIA's proprietary binary drivers
always support the latest RHEL. RHEL workstations for 3D rendering is
one major reason why NVIDIA is providing drivers for the Linux platform.

For instance, this is NVIDIA driver 390.30 on my Dell Precision 7510:

What error do you see when you are trying to install the NVIDIA's driver
with a vanilla CentOS kernel?
