Inside of Knowledge Model KPI definitions I would like to create an parameterized "abstract" base KPI Formula. Is there a way to "hide" a KPI of knowledgemodel to be used in anything else outside ? Similar to private variables/methods?

My plan is to have one "generalized abstract" KPI which in turn is being called in a parameterized way by a number of different other KPIs. So that I only have to define the PQL once but can use the KPI directly in Frontend

I however would like to hide said "abstract" KPI when Knowledge Model is being used, as it should only be used. Is there some kind of parameter that can be set in YAML definition of an KPI that makes it "private" ?
