LSM9DS1 magnetometer interrupts - open-drain or push/pull?

The LSM9DS1 data sheet shows that the accelerometer/gyroscope module's two interrupts can be configured either as open-drain or push/pull.  However, I am missing the description of the magnetometer module's interrupt.  I assume that means it is fixed and cannot be user-configured.  Is it fixed as open-drain type, or as push/pull type?

The DRDY_M (Magnetic sensor data ready) pin is push-pull, with active high level.

Thanks, that helps.  But I was actually asking about the magnetometer interrupt, Pin 10, INT_M.  I couldn't find anything in the data sheet saying whether it's push-pull or open drain.  The active level (high/low) can be configured in software but not, apparently, the output type.  Do you know which it is?

The INT_M interrupt pin is also push-pull.
