SCCM Task Sequence for BIOS (Legacy) to UEFI with secure boot ON.

[jockey]

I'm trying to deploy a task sequence of Win 10 1607, for windows 10 compatible systems. I am trying on dell systems with my SCCM 1710 (integrated with MDT). In the same Task Sequence, I am trying BIOS to UEFI and secure boot ON.  Can we do this. DO we have any paticular method to change systems (BIOS to UEFI and secure boot ON) Can someone, please help me on this.

i'd recommend you look at the work of fellow MVP,  MikeTerrill, as he's blogged this exact scenario very well.
