Is it possible to short sell call or put option?

I want to sell OTM call or put of bank nifty on expiry day bcoz i know it will be zero if spot price not reach at that strike price. My question is that i want to use margin using BO or CO ; for that there is any changes made by zerodha?
Or other rules implemented by NSE for shorting OTM call or put on expiry of bank nifty
