The "Customer Experience Improvement Program" setting has no bearing on if the Eset telemetry module is installed. I have this setting disabled and the telemetry module is installed on my EIS 13.0.24 device.
So the answer to this question:
Perhaps it relates to pre-release update status? I have this enabled on my Eset installation. However, I believe this module is installed on all Eset installations unless manually or third party software removed. Are you using any third party privacy based software on the device that is missing the telemetry module?
