There's a point in life where you have to start doing things you love instead of things you "have" to do. As a premed, you "have" to shadow, volunteer, get clinical experience, and kill your grades. If you're shooting for Hopkins, you have to do research.
Taking CS or behavioral health courses is not one of these "have to" things. If you like it, take it. If you think it will further your career, and the sacrifice in your free time is worth it to you, do it. If the idea of taking these classes is gross to you, just chill, you're a senior.
Like Mr. Smile said, just do what you want. You can't possibly min/max your app for each individual medical school.
Edit: you can also approach this as a gunner and say you're going to be the most optimal applicant Hopkins has ever seen, take classes you have no interest in, etc. Maybe that's worth it to you. But just remember, that MD diploma from Hopkins isn't going to visit you on your deathbed or keep you warm at night. There's no right answer here, but just make sure you don't throw away life chasing the "perfect" app.
