Setting PXE NIC Boot order

I have several servers i need to set the PXE boot order on the server. I know you can use the Setbootorder utility to set the RBSU's Boot order to pxe usb hd etc, however i need to set the PXE NIC boot order on the server IE.

Right now its set to

1. Onboard Nic 1
2. Onboard Nic 2
3. HP 530SFP+ Nic 1
4. HP 530SFP+ Nic 2

and needs to change to

1. HP 530SFP+ Nic 1
2. Onboard Nic 1
3. Onboard Nic 2

Anyone know a way other than touching each server? (we have ~30 and off site)
