How to disconnect the Wall parameter: "Top is Attached" with dynamo?

how can i disconnect the Wall parameter “Top is Attached” ?
according the Parameter.StorageType Node the value is a Integer.
or
do we need some python to launch the Detach the top command?
(i dont have much experience with python)

Hi @Nico_Stegeman

Unfortunately it is not possible to access read only parameters (Top is Attached…) in Revit API due to its limitations.
