I had the exact same issue deploying to a Dell Venue 11 Pro tablet (well actually 60 total). For some reason, even though the processor shows as 64-Bit architecture under "System" in the OS, I cannot deploy 64-Bit OS to it, it fails saying the architecture doesn't support it so I'm assuming its limited to 32-Bit since that's what was on it when purchased as well. Either way, doesn't matter, these only came with 2GB of RAM.
* To answer your question about the error, its due to "Secure Boot" being enabled in the BIOS. Disable this feature and viola!
* I am unaware of a way to have a task sequence that can do both 32-bit / 64- bit OSD so I created a whole new task sequence for 32-Bit deployments and attached a x86 boot image under the Properties of the task sequence, all works well. If your OSD still fails, its because you need drivers.
* I also had to add drivers for the docking station's NIC which I found here:

( Older winpe files here on the main page: http://en.community.dell.com/techcenter/enterprise-client/w/wiki/2065 )
That should be everything, the deployment is super slow compared to a normal laptop, I'm assuming its due to the hardware of tablet and dock. But it is working.
Hopefully this helps someone who comes across this older thread.
