Is there a way I can change the way I stutter?

Is there a way I can change the way I stutter? So when I feel a block I normally don’t stutter like how most people do. I either pause, say uhm, or keep repeating the word (not syllable) and then pause for a second. I want the stutter where you just repeat the syllable super fast like how the guy “drew lynch” has. It makes it seem less difficult to get passed the stutter and stuff. Is there anyway I can change it? Cause I don’t really think about how I do it I just do it
