Turning off floodlights when having a party?

Our floodlights are in areas of the backyard that get heavy traffic during parties. We have other lights installed to create more ambient settings, but the floodlight automatically turns on with motion ruining the mood we are trying to create. I haven’t figured out a setting to completely turn off the floodlight function during these events. Every setting I tried seems to revert within a two minute cycle back to motion sensing and lights turn on with slight motion. Please help me choose the right setting.
