This is assuming you meant officer career directly related to computer science as a field of study. CS does not constrain your service assignment choices and you can commission in almost any community, with a few exceptions (METOC, CEC, Med Corps).
There is no computer science minor. Only language minors are available. If I remember correctly, a CS/IT dual major is only a difference of 3-4 classes, and is the easiest of all dual major options to achieve without validation. CS/EE, CS/CY, and CS/CE are also possible depending on factors like validation and plebe year academic performance.
I saw someone do Aero/CS, so nothing is really off the table if you have some prior experience and can validate more than a few classes.
