Yes, just use camera and lens on mount and align through live view. Make sure you are correct with the star you are aligning with. Best to use single bright stars that are easiliy identified . But otherwise the star choice makes little difference. Though stars wide apart across the sky should give a better alignment result. Balancing the gear is important too as front /rear heavy will affect tracking.
Also dont just set the camera to every suggestion you see, you need to test them all and figure out what works best for your equipment. try using slightly longer exposures until you start star trailing, start at a short exposure time first and try several to find where you can photograph and get round stars then increase one increment and test again until the stars start to trail, then you can start increasing ISO similarly until the noise is obvious. Those are the fixed manual settings for your specific equipment.
Experiment and learn.
