F1 dropbox - called for an interview [I'm not in India currently]

I’m in the US & sent my docs over to my parents who dropped it off at the consulate on 26th September. The consulate gets back to me in 1 week, there is no mention of 221 (g) and visa status hasn’t been approved or rejected, but I have been called for an interview on 13th October 2022.

Now I am in the US and cannot travel at such short notice. What happens to my passport in that case? I’d like it back instead so that I can apply for a different country & skip this F-1 renewal for now

The appointment confirmation letter literally states that you don’t have to drop off documents yourself. Please advice out of that
