The short answer to your question is that YOU DON'T TECHNICALLY NEED TO DO ANYTHING AT THIS POINT.
Some agencies have you sign title to eliminate a little work for that agency. The Judge on your case signed a Court Order that legally removed your ownership rights of that vehicle already. That means the agency will just present a certified copy of that Court Order to the Motor Vehicle Title Clerk. A new title will be issued in the agency's name so it can be used by the agency, sold at auction, etc.
If you want, you certainly can send the BMV a typed letter by certified mail advising that you are no longer the true and legal owner of that vehicle. Reference the Court case, Judge, and forfeiture Order in the letter. Enclose a copy of that Court Order if you can. Yout lawyer, the Bailiff, or the Clerk of Courts can get you a copy.
I hope this answers yoyr question. Good luck in the case and beyond!
