I do not know the model, But most drills have a key or a self lock, with a key, you do not have to worry about motor, so I will assume not that. So a self lock, a broken bit should be no different to any other, on my cordless drill, I do not need to hold the bit to lock it, on my corded, I have a button to push to lock the shaft. NOT knowing your drill, Other way. But you need to be careful. You will see on your drill, vent holes. with a fan below, I have when desperate, Used a long thin screwdriver blade, and blocked the fan blades. They are connected to the motor, so locks the motor. You need to get as much support for the blades as possible, even using a few screwdrivers, to avoid damage, But as a last resort.
