How do I enable keyboard/mouse + controller at the same time?

I like putting a controller near me so I know when the controller is vibrating during cutscenes - as developers usually put in custom vibrations to match what's going on in the cutscene.
However, Destiny 2 does not do this. As soon as I use keyboard/mouse, the controller falls silent. Is there any way to enable this?


Solution 1:

This is not possible. I tried it out the other night, and as I suspected using either control set will swap the controls over exclusively to that set.
