Unfortunately too much time has passed. You accepted a plea. After accepting guilt you do have the right to post conviction relief (PCR) if there is a manifest injustice (new evidence, someone was untruthful with you, ineffective assistance of counsel…). This must be filed within 90 days of your sentencing on the guilty plea.
Hopefully another attorney has a better answer, but I think the conviction will remain.

Once you've entered into and the court has accepted your plea agreement, you are entitled to file an appeal for post conviction relief within 90 days. However, because appellate issues are a specialized area of criminal law, it's important to consult an appeals attorney who can review the facts in your case specifically to determine if any other remedies are available. Best of luck to you!
