Most of the configurations in the Felix Console are required for AEM To work properly. Unless you are following a specific document that tells you what to do in order to perform a use case, i recommend not modifying these values.
An example of modifying a configuration in the felix console in order to perform an AEM use case can be found in this community article:
Querying Adobe Experience Manager 6 data using the Sling getServiceResourceResolver method
But as I mentioned - unless you are following an article to perform a use case - i would not modify any configuration.
