Unable to do intraday in F and M groups of stocks on Zerodha

Hello everyone, I am unable to do intraday trading in securities which are under F and M groups of BSE on Zerodha. It is showing error that intraday is not allowed. Can anyone tell me the reason why there are not allowing me to do intraday. When I searched for reasons, in support it is written that there is a possibility of short delivery but I do not think there is chance of short delivery in intraday. Also many securities in the mentioned groups are highly active and traded. Also, I am ready to pay the penalty in case there is short delivery.

Zerodha should make a consent form in which groups a client wants to trade and then it will all be client’s responsibility.

I am fully aware of the risks, so Zerodha, kindly enable the intraday trading in F and M groups of BSE.
Thanks
