What your car has is the ”Front License Plate Frame (6W3)”. What you want it to have is the “Front Grille Panel (6W9)”. As you said these were options installed based on the appropriate state laws. I don’t think you can just remove the center license plate section, but I may be wrong. I’m sure there is an actual Audi part number. In the meantime just decorate it for Christmas until you get the part.
