A bit of a PITA, but there’s a hatch release button to the left of the headlight knob. You can then just push open the hatch. (I have a Badlands with the Tech Package, so I don’t know if it’s trim/package specific or universal across the entire BS line.)
Also, on the inside hatch panel in the center there’s a pop-out panel. I’m not positive, but I bet it’s an emergency release for the hatch.
