MIS not allowed for a specific stock

For a specific stock, MIS has not been allowed. It was probably put in that way during the dividend period. However even long after that period it does not allow. The stock is Graphite India. Is it normal for some stocks to be like that?

However when i tried through another broker ( there nothing called MIS) it allows short sell. Through that broker, we sell it just like the stocks that we have in our account.

Brokers can implement restriction based on stock volatility

Infact one should not intraday in heg and graphite
