I’d like to get some clarity on your current situation. Is the below statement true?
“You cannot PXE boot” on your Hyper-V virtual machine
If the above statement is true proceed with the following questions.

• Have you been able to PXE boot into another boot image on the virtual machine or is it the first time you are trying PXE boot.
• Have you tried PXE booting into a normal physical desktop or a laptop.

Reason for the above questions : Setting up PXE boot on hyper-v is a bit complex. You have to create a virtual switch and use a Legacy network adapter. You can find some instructions here https://www.danielengberg.com/start-pxe-over-ipv4-hyper-v-machine/
Also, please confirm the ADK version installed on your SCCM server.
