Dell Display Manager 2.0, Install Parameters

With the old Display Manager (1.x by EnTech) there was a readme/documentation of possible install parameters located at "C:\Program Files (x86)\Dell\Dell Display Manager\" , is a documentation available for DDM 2.0, can't find it in the according Dell directory, neither within ProgramData or Program Files

Is there a parameter for a silent uninstall of the old DDM to add to calling the uninstall string "C:\Program Files (x86)\Dell\Dell Display Manager\unins000.exe"?
