Applying to UNC undecided?

I am applying out of state to my chances are already small. I’m not totally sure of the major that I want to study in college and I was wondering if applying undecided would hurt my chances of getting in?
I have a 4.23 gpa and 2000 sat (I’m still retaking it once to attempt to improve my score) I have a bunch of volunteer hours and work many hours per week bouncing back between three jobs so hopefully that helps me out a bit.
I know my grades and scores aren’t usually what is expected there especially for out of state but I am still planning to apply since it is my dream school. I’m wondering if the undecided major would hurt my already slim chances? Thanks!
