This is one thing that differs person to person I feel like. How comfortable are you with your stutter? How severe is it? Do you get by without people noticing, or is it undeniable? Overtime as mine got less severe and more on the mild side (I’m mostly fluent, but still stutter around 1 time per sentence) I became more comfortable when I just got it out there “hey, I stutter, it’s not a big deal”. For me, this would be a great time to get it out in the open, use it in a fun fact in some way (it’s a uni intro so odds are you are gonna have to share a fun fact about yourself). If you aren’t more comfortable in the same ways I am, think about what makes you feel more comfortable with it. Is it easier for you to prep what you are going to say? Is it easier for you if you talk to the instructor first? This is one of those situations you gotta know yourself
