Main Cam (Effects - Bloom , vignette)
Second Cam (Effect - Bloom)
Are the cameras in different positions? You can make the Post Processing Volume Local and it will only affect cameras within that local area.
Or you can put the post processing objects on different layers, the camera allows you to define which layer is used for Volume components.
