One would hope you consult the appropriate flight manual, not information manual. The flight manual is approved for the specific aircraft.
The cessna info manual these days IS the approved flight manual.
Thank Christ we can get away from the old typed CASA manuals! (Although the TO/Land charts were OK)
Back to original question, I would suggest if you have more than (the short field figure) / .9 available, ie the nil flap distance before the 10% reduction, then you could use a nil flap take-off.
