Protection for Piezography Pro Matte Prints

Hello, new to printing with Piezography Pro, two weeks new! I print on an Epson 3800 and have the Piezography Pro Matte inks loaded, I don’t print Glossy at all. My question is I am finding the surface of a dried, ( 24 hours minimum ), print still to be very fragile, it is easily marked, so is there a protective coating that can be applied to the prints to help with that?
