Switch Nouveau driver to Intel driver

Dear Everybody

I have set-up a RHEL 8.0 dual system with ThinkPad P52 4K version using Xeon E-2176M & Intel UHD Graphics P630. Unfortunately, I can only use Nouveau driver which means only NVIDIA Quadro P2000 can work, but this is not power saving and every time when I boot to RHEL 8.0, I need set discrete Nvidia card in BIOS, so I want to know how to set-up only using Intel UHD Graphics P630 for display so in BIOS I can still using the hybrid setting.

Please anybody can give me some assistance with this display issue.
