Per Object Motion Blur?

I've searched for this for a long while now, but every question I see asking it has not gotten a solution. Is there a way to apply motion blur to a single object only, and not the camera? So that nothing else but that one object blurs, and it only blurs when it moves, and not the camera?

What I'm looking for is something like a tracer effect, but more like an actual detailed blur and not just a simple trail texture. I've tried using Amplify Motion from the asset store, but it's not the type of blur I'm trying to achieve. I need a longer, more drawn-out blur, just like Unity's original motion blur image effect.

I've played around with layers, but still haven't been able to get the blur to only work on a specific object and ignore everything else.

Does anyone have any ideas? I've seen motion vectors mentioned before, but I don't know anything about these, and I haven't been able to find an actual explanation on how to use them.
