If you want to land shorter, plant the aircraft down on the ground at a light descent rate after the flare, get the nose down (for tri gear) to kill lift so you can start using brakes. (Unless its some aircraft where aerodynamic braking were better than wheel brakes.)
I strongly advise you against this. Pushing the nose down will mean that you become a wheelbarrow, the main wheels kept light on the ground by the main plane above. you are very vulnerable to gusty conditions by doing this especially if the surface is wet. Braking will not become fully effective until the aircraft has slowed. By holding the nose up you induce aerodynamic braking plus with the downforce from the tail plane also increasing the weight of the main wheels and friction and therefore the braking when it becomes appropriate.
You can be assured that aerodynamic braking is many times more effective than the wheel brakes during the early stages of the landing.
