I want to make sure this original question wasn't misunderstood. When you mean "remove" your email address, do you just not want it shown on the UI making the screen simply look cluttered? If so, the answer is of course yes. You just go into the driver profile settings, then under "Name" in the fillable right portion of the screen you just remove the email address, and type in whatever you want shown. This retains the cloud profile email address on the left hand side but overrides what is shown on the screen.
