The entire door shelving can be removed. Fold back the door gasket and unscrew the screws that hold the door shelves and gasket assembly on. Remove the entire molded door shelves and door gasket assembly. You will see the door gasket wraps over and around the outer edge of the shelving such that the gasket is sandwiched between the molded door shelves and the door when assembled. Remove the door gasket, making sure to mark the top of the gasket. The gasket should look like a picture frame now. The gasket will leak if re-installed up-side-down. Ask me how I know.
With a utility knife, cut out the molded door shelves just a little inside of where the screws go through the shelf molding material. Once the shelves are cut out you will be left with the outer edge of the shelving material with the screw holes in it that also looks like a picture frame. Make sure you mark right side up. The door has a cardboard filler with insulation behind it. This can be covered with stick on vinyl shelf paper for appearance.
Carefully re-install the gasket over the outer edge of the molded frame, insuring the gasket fits snugly over and behind the frame. Carefully re-attach the gasket / shelf frame assembly, making sure not to screw any one screw down tight until all screws and loosely installed. This allows you to adjust the gasket for a snug fit. Tighten but do not over tighten the screws.
This will totally remove the door shelves and may give you the necessary space you need. I do not have the exact mini fridge you do but both the mini fridges I set up for fermentation chambers were built the same way.
Hope this helps.
