Yes, you can! All you have to do is keep your finger on your mouse or between the clicks.
While clicking, do not take your finger far away from the button for the next clicks. Keep your fingertip connected with the button while clicking.
Another thing that is worth mentioning is to try to click lightly. Make sure you are not putting too much pressure on the button. When you put a force on it, the mouse may slide out of position that can affect your CPS score badly.
