You can increase knee flexion when squatting by leading with the knees bending first or minimizing knee flexion by leading with the hips bending first.
Learning to squat takes some time to learn and some experimenting. It's not just moving a weight on your shoulders up and down. There is NO one way that is perfect. If you normally do full ATG squats with 500 lbs for reps, throw 700 on the bar and do half squats for the same number of reps. The next day you'll have a new appriciation for half squats. Full development will come only from different variations of a movement. There are numerous ways to squat. Experiment and don't be afraid to try something different.
Very well said, as usual.
