Hey guys we just ran into this same exact problem. We found that if you disable DMA Protection in the BIOS it will PXE boot no problem. Just wanted to leave this out there for you to try.

RE: PXE boot issue with HP Probook 450 G8 (Realtek Nic)
@george1421 Understood.
For us it’s just extra steps we try to eliminate. We are a pretty large school district with over 65K students and 10K employees and a lot of machines. We have more then once had to re-image an entire campus because a virus outbreak and being able to push an image to a school and just telling them to reboot has saved us a lot of time in the past. Thankfully this hasn’t been an issue in a long time. Maybe times are changing and UEFI is going to force our hand…
