Gain on Shares in holdings in demat account

I have 400 shares of Reliance Industries d no plans o sell it in near future ,can I be able to leverage the same other than pledging the stock. Can any one guide me with an illustration on how can I do something out of it.My knowledge is limited to MIS daily trades and NRML trades.
Expecting a detailed reply as this would help a lot out there.

You will have to pledge these to get additional margins, there are no other options at this stage.

Dear Karthik ,
If I pledge and i dont use the margin does it have a cost involved .Or If I put the question does zerodha charge any amount for pledging the shares other than the initial per Stock cost of 60.
