Onedrive for business - hide “Always keep on this device” in explorer context menu

Hi,

we are searching for a free solution to hide the onedrive for business "Always keep on this device" item in Windows explorer context menu.

We are using Citrix multi-user environments (VAD) and fslogix profile container and it is necessary to control and reduce storage increase on the workers and profiles.

Does anyone have the same problem or issue and perhaps a solution?
For example, Storage Sense, is not applicable for us. 

We have also not found a way to hide this entry via GPO or registry.

Thanks and kind regards,

Bernd
