Engine DJ Desktop is library preparation software, not performance software. Well, not to say you can’t use it as hobbled performance software as @Parysatis has posted (https://community.enginedj.com/t/engine-dj-as-a-performance-software/58200).
There is quantize in the desktop version to assist in setting cues and loops. Choose the gear symbol on the top right and Cue/Loop Quantization in the Performance tab.
If you mean Engine OS on the players, then @djdragon has answered that.
