A nose is a three-dimensional object in the shape of a three sided pyramid. If you adjust only one aspect of the nose, you may create disharmony. In your situation, unless your bump is extremely small, shaving it down may actually cause the middle one-third of your nose to look wider. This will give your nose a more globular, indistinct look.
Your profile will be better, but people looking at you head-on will see something that just doesn't fit. In this situation your surgeon then has to narrow the bones to restore symmetry. But, now you have a narrow body to your nose, and the tip, which was left alone, looks too wide! It can start a vicious cycle.
Give your surgeon the leeway necessary to help you make a good decision in terms of the procedure(s) that would obtain your surgical goals. Rhinoplasty is considered the hardest cosmetic surgical procedure to perform so make sure your surgeon has a comfortable level of experience.
Good luck.
