Will the hump be smoothed out into a straight line with filler?

My nose isn't particularly low overall, but the middle bone of the bridge protrudes slightly, and the areas just above and below it are subtly sunken, giving it a hump shape. This bothers me every time I look at my profile. When I take photos, my nose line doesn't drop as a smooth straight line or a gentle curve; instead, it feels like it catches in the middle, making my impression look masculine and sharp—which is my complex. However, I haven't been able to touch it because I'm afraid of the cost and the recovery period for major surgery like bone reduction or implant insertion. So, I am looking into a nose bridge correction procedure that involves using a small amount of filler only to fill the sunken area below the glabella and just above the tip of the nose to gently smooth out the hump curve. Would this maintain the smooth nose bridge line I want over time, without the "Avatar effect" where the filler spreads sideways and makes the bridge appear thicker?
