Using hydrogen peroxide in RA-4 developer for more contrast and saturation

[legstowalkmyself]

Been using 20% hydrogen peroxide in my developer when RA-4 printing Ultramax 400, any other niche tips for increasing contrast and saturation?

I really want that slide film natgeo look with negative film

You still want more contrast? Looking at the picture I'd think of less contrast....

You can try double development, but there is a limit where a print can go. Developing too much in excess only leads to (chemical) fogging.There are no miracles in the darkroom.
