Actually, Steve is right. If an el7.6 kernel is not available to yum, 
then all 'el7.6' packages are excluded, including the 
nvidia-x11-drv-390xx package required in this case.

The workaround is to (temporarily) enable vault so the old el7.6 kernel 
is visible to yum, or leave a copy of the older el7.6 kernel installed 
on the system.

This issue is caused by a fundamental difference between RHEL where all 
packages are available in a single channel, and CentOS where only the 
latest point release packages are available and all older content is 
moved to the vault. In this case the plugin was developed on and written 
for RHEL, and CentOS' divergence breaks compatibility.
