i think the best is to change the property of the icon to start pd with the good flags, so that you can create many icon with differents flags.

but since you don't like this, you should : in pd / startup
add in "startup flags" :
-noaudio -audiobuf 0 -mididev 3
than : "save all setting" and it should work for next reboot...
