Massiv uninstall ddpe from 2500 computer

Hi,

We want to massively uninstall dell encryption on our fleet.

we have multiple version of ddpe 10.4 to 11.5 and we try to uninstall with dell encryption uninstaller from command line.

the uninstallation goes through both sccm and worskpace one via profil.

• currently all uninstallation attempts have failed. and when in rare cases the uninstallation is successful we still have traces in the registry and in the system folder (cmgffe.sys).

we need a technical expert to script this uninstallation. we have a contract with the french support of dell  but we receive no help.
