Can i place cnc orders with the margin from pledged shares

I know that the margin available by pledging securities is allowed only to trade in derivatives ( that too with some restrictions ). What I want to know is if system allows me to place the orders based on the margin money available because of pledged securities. I will settle the bill the same day or the next day without fail. I want this feature because I don’t want to keep large amount of money in the trading account which does not carry any interest. Please let me know if there are any other discount brokers who will let me do that if zerodha does not permit. Thanks in advance.
