Post-Process Volume on just 1 actor

Is it possible to have post-process effects active on just one actor ?
Using a brush could make the volume bleed onto other objects.
I’m trying to have bloom onto only one actor, and so far I can’t restreign it.
I would like to have the possibility to use custom depth stencils to do that for volumes.
Thanks for reading and answering.
