Questions on motion detection and managing floods - as well as three way switch

I'm looking to replace two flood lights on my deck. These do not have motion detection. Was considering one with a camera and one smart wired flood light. Currently my floods are on a three way switch. Here's my questions:- Can I disable motion detection and turn on the lights when needed. To prevent them coming on often in the night due to nighttime critters and trees swinging...- Can I use the switches to turn on the floods vs having to use the app or rely on motion detection (eg. having people over and just want them on... and my wife wanting to just hit a switch an walk outside - assuming motion is disabled).-Any issues with three way switches?Thanks
