I think you've got the wrong idea about eduroam. John Hodrien was just
using it as a real world example of WPA2-enterprise in action. It's a
private network for academic institutions - it allows members of
Universities around the world to gain access to the wifi at a local
University they are visiting. It's not a public wifi service.
It's a convenience - a very, very convenient convenience. If you don't
want someone tracking where you are, then don't use it. But TBH if you
are visiting another university, then in general your location is
known!

Your customers wouldn't be able to use it anyway

So restrict based on MAC address at the PXE boot stage.
The PXE protocol, as far as I can see, has no concept of authorisation
- although its certainly possible to introduce it after PXE has done
its bit (but before imaging or whatever).
You may be better off with authenticating the DHCP using RADIUS, but
it's a complex process which, by its very nature, requires some form of
non-authenticated network access.
