Please Help - NVIDIA Driver installation on RedHat 7.3 | ThinkPad P51

Trying to evaluate Red Hat Enterprise Workstation, but got stuck at the very beginning - external monitor is not working via bundled driver, and I'm unable to install NVIDIA driver. Have tried to follow:

and ELRepo:

on 7.3 and 7.4 beta, but the result is still the same - boot hangs somewhere around:

[OK] Started GNOME Display Manager
[OK] Started Visualization daemon
[OK] Started Postfix mail transport agent

HW is fine, Mint XFCE (second SSD) is working flawlessly using NVIDIA Driver.

Conf:

ThinkPad P51 Quadro Workstation
Xeon E3-1535M v6
NVIDIA Quadro M2200
RAM 64GB ECC

Any ideas?
