The safe answer would be to bleed the whole system. The right front caliper gets fluid from both the front and rear brake systems, and has two bleeder valves on it, so you can bleed both circuits.
Having said that, it wouldn't hurt to attempt to just bleed that caliper (both circuits) and see if you could get away with it. You will have to read the manual to see which valve is connected to the front brake lever and which bleeder valve is connected to the rear. (One uses an 8mm wrench and the other a 10mm). If memory serves, the upper bleeder on the RF is connected to the front brake circuit and the lower is connected to the rear (pedal) circuit. It will either work or it won't. If it doesn't you will have squishy brakes and will just have to go back and bleed the whole system from start to finish.
