No. The SAT I is an exam for all college-bound students (yes, some colleges don’t require it, but most do). That’s for anyone who intends to major in anything.
But I think you are thinking of different SAT tests. There are “SAT IIs,” which are specialized tests in various subjects (math, physics, chemistry, many non-English languages, US history, etc.), which you should take if you intend to apply to the more competitive or “elite” US universities (think Harvard, Yale, Stanford, MIT, and others). You should check with the schools to which you intend to apply to see if you need to take the SAT IIs. If you do, it is a good idea to take the SAT II in the subject in which you intend to major (e.g., if you intend to major in chemistry, take the chemistry SAT II). Good luck!
