How to Safely Adjust Vertical Spacing in Relume Component Header36 Without Breaking Styles

I’m using relume component header36. My boss thinks the section is too deep vertically. I don’t want to screw up any relume classes that I shouldn’t like padding etc. so can I add a new class to the component and change the vertical sizing to shorten it up? What is the best/safest way to change the depth of this component header36. I’m a newbie at this so I wanted to ask first..
