3-prong to 4-prong conversion - EXTRA MISLABELLED WIRES - Dryer cable upgrade and installation
No, No, No! In this day and age you never hook green (ground) wires to white (neutral) wires. That's why you're going to a 4 prong from a 3 prong... so you can separate them. You need to determine where those green wires are hooked up that appear to go behind the terminal block to make sure they are not jumped to the neutral, white wire. If they are, disconnect them and just remove them completely as they are not needed because of the new ground wire in the plug.
