Many universities will allow you to change which course you plan to study.
If the course you would like to switch to is at the same university that you already have an offer from the best thing to do is to contact their Admissions department.
However, if you would like to apply for a course at a different university from where you already have an offer, you'll need to release yourself from that offer before you can apply to another university.
