There are multiple possible issues -- see here:

@ejn63​ That interface shows the old BIOS settings and I have older laptops that work, but these newer XPS series do not for some reason.

What model XPS do you have, and what network adapter?  And is your PXE boot image UEFI-compliant?

@ejn63​ 

XPS 15 (9530)

Killer 1650/AX211,B,A,FIORAN seem to be wireless card

If the other laptop worked, it should be compliant

Most imaging is done over a wired connection -- wireless imaging is another matter entirely.  What was "the other model" system?

Have you tried connecting a USB-C to Ethernet adapter to see if the UEFI boot sequence detects the PXE image?

As of now, I've only tested the overwired connection, but it does not work.

We don't have any wireless imaging incorporated. The issue is I can't get the PXE to show up on the boot manager.
