I don't mean to be snarky, but you are in control of what you are doing. You can break the habit of leading with your hips by starting to flex the knees and the hips at the same time.I guess what i'm asking how can i go about breaking the habit of leading with my hips so my knees can go out first?
You need to go deeper and a pair of weightlifting shoes should be in your future. Your knees should come a little further forward than they do by halfway about down.
