I’m looking for assistance with a script that can reduce or increase the height levels of a normal map using a slider. Similar to the way you can change the intensity of a height map by reducing the brightness of the the greyscale to reduce the height. I’m looking to perform a similar operation but for a normal map.
Multiply the normal maps R and G channels with a multiplier and if you plug something to B, multiply it by one. Leave B as is. I think this will scale the strength slightly but it will not change the area of the effect as would happen if you altered the “intensity” in some normal map making app that would make the emboss area spread wider etc. But it will work just fine for most situations.

In shader graph there is a normal Strength node that handles scaling the normal map for you.
You can just pipe a multipler value in it.
