Apply different effects on different cameras

I'm using the Post-processing Stack v2 under Unity 2017.4.10f1.
Suppose that I want to apply a blur effect only on certain objects (for example, foreground objects). I've marked these objects with a specific Layer (for example Blur), and I've two cameras, one configured to render all layers except Blur and one configured to only render the layer Blur (through Culling Mask).
On the second camera I've added a Post Process Layer and a Post Process Volume, but the effect apply to the whole objects, not only the ones marked with the Blur layer.
Whit this Post-processing Stack it's possible to achieve what I said above? In general with this stack it's possible to have different effect applied to different cameras?
Otherwise how can I achieve this result?
Thanks.
