Exhaust gases leave the turbo thru the down pipe, the down pipe has a small pipe that connects to the back of the EGR cooler. Some of the exhaust gases pass thru the EGR cooler to the intake. These gases are cooled in the EGR cooler before they pass thru the EGR valve, then to the intake. The EGR valve gets commands from the PCM on when to open and close.
So if you just put a plate on where the EGR valve goes and don't block off the back of the EGR cooler at the down pipe, then you will have exhaust gases constantly pushed into the intake. NOT GOOD!
You could put a plate on the EGR valve, it will run like poop.
