How to hide specific panels

I have a home dashboard in which I have set threshold values for different metrics.
I have list of vm and I have 3 columns for each vm which are Infra, database, and application monitoring. according to the threshold I have set color coding as red(serious), yellow(medium), and green(ok).
I want to show non green items on the dashboard and want to hide the green panels. refresh rate of my dashboard is 5 mins. how can I do it?

I am also interested to learn the solution for this . appreciate if anyone have a solution on doing this
