No, because tummy tuck will make the skin in your abdomen different from the skin in other parts of your body, which will accelerate the aging of your skin. Although it has a certain effect, it is not obvious. The best way to tuck your knees is to do sit-ups and always sit upright, which is better. As long as you insist on it often, I believe you can get rid of all the fat in your abdomen without pleating.
