How do I disable the messages the "Display Brightness" is using significant energy?

I just got a new 16", i9-based MacBook Pro running 10.15.6 Catalina. Under Energy Saver, it complains that Display Brightness is using significant energy while I am on AC power. I want that complaint to go away. I know if I dim the display to 75% or less, it goes away, but I want the display to be at 100%. 100% is easier on the eyes and it is what I paid for. If the display is not designed to be used at 100%, then it should not go to 100%.

How do I make that message go away permanently, or at least permanently while on battery? It is a false warning which requires no action on my part, and it distracts from any real messages under Energy Saver. It simply encourages me to ignore everything under it.

Thanks.
