Disable Xbox Analog Stick?

hey guy, today i finished my arcade stick, wiring the dpad took like forever, it worked fine for a litte bit but then i noticed that because of my small case the left and right bumper was constanly pushed wich interfered with some control configurations. so i removed the inside of it so it couldnt get pushed down anymore… now the analog movement is freaking me out… it constantly moves to the right… wenn i tough the metal part of it, it goes crazy into every direction…

so is there a way to disable the left analog stick/bumber completely?
