In speech therapy this is called 'Avoidance Behaviour' which is deadly not recommended in the therapy cuz not only will it probably get you obsessed with speech fluency which is likely to gonna be debilitating but also is impossible cuz if you can completely overcome stuttering, be it 'Avoidance Behaviour' or not, stuttering is not a problem to you at all but if you can't then you are using changing words, keeping silence, playing dumb and similar methods to avoid revealing stuttering but this must be limiting your expressions so therapists will not recommend avoiding.
