NYU health insurance

Hii!! I’m currently an incoming freshman to nyu, and I have health insurance already but it’s only covered in Illinois, im planning on switching to blue cross health insurance but the enrollment doesn’t open until mid October, and nyu insurance waiver deadline is September 30th. Do you know if there is any nyu will exempt from their student health insurance, I don’t want to pay 1800 for it because that’s too expensive.
