How to prevent UEFI drive partitioning on PXE boot MDT Deployment?

Previously we didn't have to do anything special because PXE booting was supposed to not support UEFI. However, I just imaged a laptop using MDT 2012 and WDS PXE boot deployment and when the image was finished, I noticed our encryption software was not working.
When I looked in disk management I saw that there was a 500MB system partition that's created when EFI booting is enabled. The disk encryption software is not compatible with GPT disks, so it failed.
What can we do to ensure PXE booting always deploys as legacy BIOS so Windows gets installed with standard MBR partitions?
I looked at a previous threads and it was the opposite question. http://social.technet.microsoft.com/Forums/en-US/winserversetup/thread/ceca6149-bedd-4860-8a7f-a1c83bf99aa4
That person was trying to enable EFI over PXE. I am trying to disable it.

you will have to change some settings in the bios of the laptop so that it either will only legacy boot or disable the network stack for EFI pxe booting.
i see a lot of motherboards come through here and most have the option now to enable efi with pxe but it is disabled by default.

There does not appear to be any option for EFI or legacy for network booting on these systems.
Maybe it is not an EFI issue. Is there anything like a check box that shouldn't be checked or anything else in MDT 2012 task sequences that triggers creating a 500MB system partition when we only intend to have a single partition that uses the entire drive?

you can either put "DoNotCreateExtraPartition=Yes" in your cs.ini or unselect create extra active partition on the format and partition step of your task sequence.
to keep MDT from making that 500MB system partition.
