Kibana v7.0.1 Infrastructure App Configurability

Hi, How can one modify what gets displayed in Kibana v7.0.1 Infrastructure App ?

Want to see used disk space pct metrics, which exist in the index.

Currently can only see CPU, Load, Memory Usage, Network.

From quick research, it is not configurable until Kibana 7.4 with Metrics Explorer ?

We added custom metrics for the Inventory View in 7.7.
