What is the fastest way to render only a certain object in the middle of many objects?

I want to have still the reflection of lights bouncing to the object, but I just don't want the rest of stuffs get rendered.

I don't want to turn on and off visibiliy in render of each objects one by one, because too many objects.

You could try using Canvasses, defining node groups to specify which elements to include.
