Groww MTF Auto Square off

Hi all, My brother had bought a stock with MTF worth ₹300,000 in total, 50% given by him and 50% by Groww. This MTF position was bought on 16th Feb,2025. So today somehow the broker sent an email and informed that “Stock (abc)will be temporarily unavailable for MTF.” My bother has active position in that stock. So, can they force hm to exit the stock like this? Broker is getting its MTF interest daily and Margins are well maintained to avoid auto square off. ⭐️So, today he got an email like this: “In line with our risk policy, (abc) will be temporarily unavailable for MTF. Exit your MTF position in (abc) now to avoid auto square-off.” Note: It is a delivery based MTF position. Not an Intraday position. Thank you
