Aye, the problem is that efi iPXE can't directly boot 6.x versions of RHEL and
CentOS, so I was trying to determine if its possible to either pass a boot
config to grub via command line or if Grub can pull the PXE space Option
209/Option 210 data so I can pass generated config for it to load.
We used a similar work around for booting Legacy PXE installs of ESXi using
PXElinux, but unfortunately, Redhat is a lot more limited.

I don't know if grub supports what you are looking for. iPXE does, though.

Sample boot.ipxe and boot.ipxe.cfg:
