Can the Sides of the Nostrils Be Cut Only Instead of a Full Surgery? (photo)

       Yes, the nostrils and alar base can be reduced, but you may want to consider tip refinement as well.   The decision is yours.  Find a plastic surgeon with ELITE credentials who performs hundreds of rhinoplasties and rhinoplasty revisions each year.  Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results.

From the photos, I see you have a wide nasal tip as well as a wide alar wide (nostril to nostril). The wide alar width can be reduced with surgery under local, However, the wide nasal tip will probably need surgery, but we are reporting on 30 cases of injectable rhinoplasty in which in some we have augmented the tip creating at the appearance of a narrower nasal tip. Injections are temporary.

Yes limiting cosmetic surgery on the nose to just the "sides of nostrils" is sometimes a very reasonable choice but your main concern is a bulbous tip.  That would not be helped with such limited surgery.  You need to begin with a personal consultation with an experienced surgeon to know your options.
