You can use a combination of the “displacer” deformer and “current state to object”
If you have sub-divisions through the displacement channel or via a “HyperNURBS” object you will need to make sure these have also been converted.
In the case of subdivisions through the material you will want to use a “HyperNURBS” object to reach the desired subdivision, then run “current state to object” or “Make editable.” then use the displacer on the resulting geometry and use “current state to object” again.
