How to cancel a FAFSA loan?

I did this last year when I transferred universities but spent about an hour on hold trying to be connected to a representative. I do not need to cancel the whole loan only part of it does anyone know if I’m able to do that online? Or should I just call and wait for eternity??? 😂 sorry I’m really impatient on the phone
