You can animate all volumes and their material properties with drivers or keyframes.

The VDB's are static volumes without any animation - you can however animate the procedural VDB materials to get a moving effect.

Simple right click a value and insert keyframe (hower and press i) or insert a driver.

All presets have a dedicated density slider on the addon N-Panel.

Make sure you have an HDRI/skytexture or lights in your scene and that you're on CYCLES in rendered view.

Restart blender or switch between Volumes & VDB's (Top of the addon N-Panel)
