Cobbler Kickstart failing on Dell 7750

We received a new Dell Precision 7750, I am able to configure the Bios with Secure Boot off and Fastboot = Through, Thunderbolt is enabled and Enabled UEFI Network Stack. It grabs the IP at the initial PXE window but then flash's a message and then goes to a blank screen. The Cobbler kickstart definitely works with other Dell laptops and desktops. The Cobbler server is RHEL 7.9, Cobbler version 2.8.5.

Does anybody know of the BIOS options that should be selected and also has anyone gotten this to work with a Dell Precision 7750?

Also anyone know if I can see the message that pops up after the PXE boot option?

Please help!!
