Yes, it's possible
⭐Use iron filings or a plotting compass to check that the steel rod is not magnetised before proceeding
⭐Wind a few dozen turns of insulated wire around the steel rod. (Leave enough wire free at either end to make connections to the power supply.)
⭐Connect the ends of the wire to the low-voltage DC power supply, so that a large current flows round the coil.
⭐Switch off the current. Test the steel rod again to see if it has become magnetised.
⭐Determine where the rod's magnetic poles are.
⭐Devise a method for magnetising the rod in the other direction.
