Yes, this can potentially violate your probation. Fortunately for you, the offense might be charged as an infraction and an infraction should not violate your probation. If you are charged with a misdemeanor, there is a good chance that you could be charged with the VOP.
You should consult with a criminal defense attorney who is familiar with the practices of your particular county DA.
Though, I am rather flabbergasted that you are on INFORMAL probation for a DV related offense! Even with a misdemeanor for PC 243(e)(1) there are usually anger management classes, often a criminal protective order, and assorted fines and fees that must often be paid. Such an offense is rarely made an informal probation issue ... but, different strokes for different counties.
