Whether you fight to suppress the stutter or find the confidence to be disfluent in front of others will not determine the progression of your stutter. But fighting to suppress it will be effortful and distressing, risks undermining your self confidence, and may exercise secondary stuttering characteristics. There's a subtle difference between fluency shaping (long-term habits while talking to increase fluency before a stutter occurs) and fluency modification (techniques to break out of a dysfluency in the moment). And there's research to support long term benefits of increased fluency from learning these strategies.
