How to create a VM with UEFI boot enabled?

Using RHVM to create a new VM, I don't see any options for specifying UEFI vs legacy BIOS boot. Are you supposed to manually supply UEFI kernel path/parameters under the Boot Options menu? I have found nothing online or in documentation related to how this gets enabled. Right now all of my VMs are legacy BIOS mode.

Thanks for the help!
