having install issue with a M4000 and red hat 7.4--case 170829-000450

The lasts post from Red Hat is there “that Nvidia M4000M gfx will fail to use nouveau driver when BIOS is set to discrete graphics mode. This is a known issue and it’s not resolved in RHEL7.4. We have an internal bug open for this issue.
Currently the bug is being tracked for RHEL7.5.” So it works with RHEL 6.9.

The Nvidia .sh script contains a bug ???
