As of now it does, at least in the current public Beta which I am running.
Install the beta. Then click on “Device” at the top. On the right panel where it says control, click on the “Printer Parts” button. The printer parts window will display and it has a drop down to select between hardened steel nozzle and stainless steel (the default). THEN the printer knows you are running a hardened steel nozzle.
Currently however, my printer device only allows me to select a .2 and a .4 nozzle which is stupid because i bought a .2 and a .6 when I purchased the printer, so why that setting is not there is just a ridiculous mistake or its Beta.
