yes, on SAVE mode at higher speed on highway, then EV or NORMAL when going Slowly ( 70 km/h or less) for town an cities. However, I would probably not go in CHARGE mode nor would I pay for any charge level 2 or level 3 (CHADEMO) for your distance, roughly 460 km back and forth.
I would stay on SAVE mode long enough, then estimate my battery usage to make sure that it is mostly all used by the time I get home, where you charge it. That’s the cheapest place to plug-in the PHEV and the car doesn’t use more gas to charge the battery on the run. Depending on your ride, you should finish with a very acceptable fuel consumption and a cheap electric charge.
