Why does RHEL 8.4/8.5 and RHEL 9.0 do not display the GUI with Intel E810 Westport Channel Adapter Enabled in BIOS Settings?

Issue

Booting fails while trying to boot with Westport Channel adapter(Intel E810 adapter) enabled in BIOS settings.
The system fails to load the GUI and is seen stuck indefinitely.

Steps to reproduce:

• Enable the slot in BIOS Settings
• Install RHEL 8.4 , RHEL 8.5, or RHEL 9.0
• Try to boot into OS after installation
