RHEL7.9 on new Dell 7750 precision laptop

This is a very confusing problem. Have installed RHEL7.9 on 5 identical Dell laptops with no real issues (Driver for internal NIC not withstanding) but this laptop began getting a blank screen on boot. When I try to do a reinstall, if I boot to a RHEL7.9 install DVD I get a blank screen, but if I use a RHEL7.8 DVD it boots into install as normal. Anyone seen this issue before. I can install 7.8 and then update to 7.9 but I am afraid it will just go back to the same issues it had before. Trying to solve the boot hang issue as it may be the same root cause. Note the laptop does have NVIDIA card installed.
