Can you change brake fluid the old fashion way of pumping the pedal and holding it down when you have psm OR DO YOU NEED THE pst2 in order to activate the valves during brake bleeding

Activating the ABS/PSM systems during bleeding is only required if you have gotten air into those systems; if you are doing a flush on an otherwise OK car, you do not need it. I would, however, suggest getting a Motive pressure bleeder to turn the process into a one person project.

As long as you do not let the hard lines drain while your are changing the flexible ones out, you should still be fine.
