Is there a way to search/filter/select layers of a clip in the animation tab?

Is there way to select all layers in the animation tab that only have two keyframes, one at the beginning and one at the end of the clip? I know that fbx on export from most software will bake keyframes for pretty much every layer of an object.

Right now I have to manually select animated layers I don't want and delete them.

Or ideally there would be a search function in animation tab and/or filters to select layers of the animation. Maybe a tool that can do it in the asset store?
