Undergraduate thesis tutors can apply for changes. However, replacement is not recommended. Because the school arrangement is based on a certain degree, if it is changed, the relationship will be a bit awkward. Moreover, every graduation thesis instructor is very responsible and attaches great importance to the writing process of graduation thesis. As long as you write, organize the literature, have your own innovative ideas, and modify and modify the paper according to the best results discussed with the teacher, you can finish it.
