It can only be expunged once you reach 70 years of age. Your only recourse is to seek a governor's pardon. They are hard to achieve and you should seek help from an experienced criminal defense attorney.
My colleagues are correct. Short answer is NO. Longer answer is maybe when you reach the age of 70. A pardon is currently the only conceivable option but given the relative recency of your convictions, a pardon is not realistic for several more years of highly productive citizenship. Sorry.
