If the professor is not on board, go higher up the chain to a department head. Ask for it to be done one on one with the professor and not in a room full of students. You can possibly do it under the preface of an ADA courtesy. I know when in college I talked with each professor at the beginning of each semester and requested that I not be called on in class to read out loud or answer questions. I explained as to why and I only had one professor who was determined to make me perform like a monkey doing tricks. After a few very awkward speaking incidents, they rarely, if ever called on me again. You must put in the effort and get good grades. Otherwise, you will be seen as some student trying to get out of doing the work. If you put in the effort, generally speaking, people work with you. If that fails, accept your fate and just do it. After you stutter your way through it, and you will, the professor will have a moment of reflection and think one of two things -- that they should not have made you do that, or grade you on your content only and not your presentation (which I guarantee will be higher since you will likely be over preparing for it). Either way it is a win for you. Also, just so you know....no one cares about presentations. You know how you are sitting there saying this is boring and that you wish class would be over? They will say the same about you. No one cares. Unless this is some doctoral dissertation, the students don't want to listen as much as you don't want to talk.
