Yes, of course, you can. Suppose you started researching a topic you chose and found out that there is nothing much you can do. Do not adhere to the same concept that does not fuel your confidence. Instead, choose a topic that has been able to convince you. Next, you know what to do. But, changing a dissertation topic can be challenging. Hence, it is advisable to choose a dissertation topic judiciously. Check the theme, read about it extensively, see whether there are enough investigative reports available or not, check whether it is open for a hearty discussion or not, and then start the work. If you are not confident, ask the Dissertation Topic Selection Experts at British Dissertation Help to help you.
