The first thing you can consider doing is turning this over to a lawyer who will get it handled. He will do this by threatening and preparing for a trial and then getting a plea bargain that he wants and that results in a plea that does not put points on the license.
She can try this herself, she can call the prosecutor ahead of time (not the judge!) explain that she has never had a ticket, and ask if she can get a "pretrial diversion", a deferred adjudication, or take defensive driving to prevent a conviction. any of those will result in a no conviction finding and thus no points.
The chances are better that she will get one of these options if she uses an attorney but certainly people get these every day without a lawyer. However, if she tried to handle it herself and the prosecutor doesn't agree then he isn't likely to agree if she then hires a lawyer so the lawyer will be forced to take it to a trial. Once prosecutor has said no, they don't like to change their minds.
If she pleads guilty without a plea bargain in advance then the judge will find her guilty and won't give her much of a sentence, likely a small fine, but she will get the points.
