Short, simple answer: yes, it is possible. However, what chances she has to have her charge reduced to a misdemeanor, change her bond, and/or obtain a probation sentence depend on the facts of her case and her criminal history. In any event, she should be discussing her case with an experienced criminal defense attorney who can assist her with obtaining a positive outcome in her case.
As Mr Bellmore stated, it is possible to get house arrest, but only if she avoids a felony conviction. Probation is another sentencing option. Lots of rural counties do no have house arrest options, so your best bet it to hire a criminal defense lawyer for your girlfriend.
