I would think, but have not tested ZFS with UEFI.

Yes.  Mount the EFI partition with msdosfs, then copy boot1.efi to 
/EFI/BOOT/.  Then comes the tricky part, getting the UEFI firmware to 
add that as a boot option.  In a Dell UEFI system, it could be added to 
the boot options, and the firmware has the user select the file from the 
EFI partition for that option.
