Artistic Depth of Field

Hello, with the removal of the Bokeh DOF from post processing volumes I was wondering if there was another way to create a fake DOF effect. In our scene we have a camera that uses cinematic DOF as per the norm but we have background assets that we want to appear blurred no matter what the lens settings are on the camera. We want to simulate the far distance blur amount effect that use to be available because now, unless there is a focused object zoomed in on, the background will always be in focus.
