Hi, Daniel.
You can remove all the "Computer Baseline" not only metrics off CDM probe but also all the metrics off all the probes on robots in under specific HUB.
Please go to HUB server which takes care your robots and do the below.
1. Deactivate PPM probe on the HUB
2. Deactivate baseline_engine probe on the HUB
3. Rename <baseline_engine>/cache_dir/metricset.txt.zip to something else.
4. Activate PPM probe on the HUB
5. Activate baseline_engine probe on the HUB
