You absolutely can do this if you go on a meditation retreat. I went to https://www.dhamma.org/en-US/courses/search though I am sure you can find other schools of meditation. My experience was that you are not allowed to talk for the duration of the course and just focus on breathing & meditation (10 days in my case). It brought a great deal of calm and focus into my life.
