You can also run this script to enable or disable the Camera Ray Visibility for all objects in the scene:

import bpy

for obj in bpy.data.objects:
    
    # toggle mesh lights
    if obj.type == 'MESH':
        nodes = obj.data.materials[0].node_tree.nodes
        for node in nodes:
            if node.type == "EMISSION":
                obj.cycles_visibility.camera = not obj.cycles_visibility.camera
     
    # toggle lamps
    if obj.type == 'LAMP':
        obj.cycles_visibility.camera = not obj.cycles_visibility.camera
