From the Modifying dice results block from the Rule book.

Important: When a die is changed or rerolled, ignore its original result and apply only the new result. This new result may be modified by other effects; however, a die that has already been rerolled cannot be rerolled again during this attack.

So if Han has already rerolled one or more dice (Using a Target lock for instance) he may not reroll those dice again.
