Adjust height levels when using normal map?

Unity Engine
1

I have a normal map whose height is too high (too bumpy) that I would like to tone down. If this were a grayscale bump map, I’d just re-import it turning down the height scale, but since its already a normal map I can’t do that. Is there any way to reduce the effect of the normal map in Unity? Or is the only way to do this to create a new normal map?

Desaturate slightly in GIMP? Use a parallax bump shader with the slider perhaps?

Thanks Targos, I wouldn’t have thought of those.
