Hi @pozlu0 ,
As far as we know, the ResourceID of the client cannot be changed manually.
It is not recommended to change the ResourceID because ResourceID is a unique identifier for a user or computer object. If the ResourceID changes, ConfigMgr will treat the device as a new device.
So if we want to change the ResourceID of the client, maybe we can uninstall and reinstall the client so that the client will get a new ResourceID.
