Can a Windows 2016 server provide two PXE boot sources?

[InteXX]

I'm here because I have very little experience with the concept of PXE boot. In fact I've only used it once or twice to restore workstation images from Server Essentials backups (re: https://windowsserveressentials.com/2014...restore/).

But I've now run into a pretty serious problem that's preventing me from running a clean Windows Enterprise install on a workstation. You can read about the whole saga here:

In a nutshell, the ISO contains files that are too big for FAT32, and apparently the UEFI on this system doesn't properly support booting to NTFS.

It's starting to look like my only option here is a network boot (at least if I want to use UEFI, that is—which I do). But I'm already running a PXE server with 2016 Essentials Server. I need to retain the current functionality; I can't get rid of it.

Is it possible to have two different PXE sources running on the same Hyper-V Gen2 VM? The first would be the native functionality built-in to Essentials, and the second would be iPXE serving up a +4GB ISO (over a gigabit Ethernet LAN). And if so, how/where would I even begin setting this up?

I'm afraid I get absolutely lost when I start to read about all of this.
