Sure you can. It just voids the warranty.
2 screws that hold the data plate on also serve as set screws to keep the big nut (rear of valve NOT the front) from turning. remove them and the data plate, set aside, get a big wrench and turn the big nut clockwise about 1/4 turn, this may do it, so test before you put the screws back in.
You may need another 1/4 turn, the valves vary a bit.
You don't see it, but the perimeter of that big brass nut is notched like a sprocket, the two set screws sit down in the valley of the sprocket, so you may want to adjust the nut slightly when you put the first screw in to get it to find home.
