Volunteering for college

Hi, I know that volunteering is a standard EC when applying to college, but should I be doing it if it’s not even related to my major? I’m debating on joining NHS, but everyone does that and generic volunteering so I feel like it’s not that special. I know people who are interested in the medical field do volunteering at hospitals, but as someone more interested in the buisness and computer science area, I’m stuck on what to do or any opportunities related to this.
