Hello
Yes if these are ADR volumes, ZPR would not affect it. Garbage collection would clear invalidated pages in time, if the cleared data is significant but this is not something you cant trigger for instance with ZPR. If you want to clear this quickly(lets say to delete all the data), you could for instance disable dedupe so that it rehydrates the data, clear's it and then re-enable it before adding more data, or just wait for garbage collection in time to do it's job.
ADR data is potentially shared in the entire pool. This is something Garbage collection does, to ensure that the data isn't used elsewhere. If it is, it obviously wont clear the data. If it can, it would invalidate the data, and then clear it with ADR garbage collection.

Hello Irsyad
Some questions:
- What kind of host mode options do you have enabled on the host groups?
- What version of ESXi?
- What version of SVOS and array are you using?
- Do you perhaps have screenshot of before and after?
Are you for instance using Host Mode Option 114 as described here:
