I would need more information in regards to the conditions of your probation and specifically your condition to have to take polygraphs to answer this question more thoroughly. If your condition is to take polygraphs on request and pass your polygraph you can be violated for failing the conditions of your probation. Usually a polygraph is used to determine the probationers' truthfulness regardless of the substance of the questions. For example if the question is "Did you have eggs for breakfast?" and you say no but in fact you had two eggs for breakfast, you are in violation of your probation because you were not truthful. Clearly eggs were not a substantive part of the crime you committed, however you were not truthful with the probation officer when they asked.
