To hide particles made in addition to an object (for example, smokeobject), you need to create a node Rendering Parameters Volatile:

Next, in the Data Name field, specify Geometry/RenderParms, where Geometry is the name of the data to be hidden.

Then, by changing the Display parameter, you can turn on/off the display of geometry. This doesn’t affect the status of the simulation.

Keep in mind that vector in the new volume source should be a merged vdb, or a space separated list of three scalar volumes.

It looks like you need to turn off Use Timestep in Volume Source when working with FLIP.
This is tested on 1, 2, 4 and 8 Dopnet Substeps for collisionvel. With the Use Timestep toggle off, the simulation was 100% correct. With it on, the sliding effect appeared.
