First of all, there is nothing wrong with Infantry. Infantry is awesome. When people think "Army" they think "Infantry."
Now, to answer your question, it is possible to get something else. Anything is possible. But what else would you qualify for? That's something to ask your recruiter.
Listen to him. He'll lay it out for you. Take a serious look at all the options available. Don't toss any MOS because everybody sweats and everything is vital for national security. That's what the military is about: national security.
Still don't like your options? If you think you can do better, maybe you can. Study your *ss off! I've met people who studied for almost a year to get the score they needed and got the job they wanted.
In the end, military or civilian, life is what you make of it.
