I have been told by ERAS that it does not, however I can't confirm that. My program has a primary care and a categorical track, and applicants often change their minds in the application process.
However, if you do apply to a second track, it really doesn't do very much. The program already has all your data. You might just want to check with the program themselves. If you've been invited for an interview, I would simply mention that you are interested in the other track, and ask what you need to do. If you were rejected by the program, I doubt that applying to another track will change that decision.
