How to get AI to change skin tone to alabaster white?

Greetings, I am new to Adobe's Firefly in Photoshop, but I have messed around with some AI image creators.  In my line of work I do 3d modeling and use photoshop for all my skins.  Based on what the player does, it can change the skin tones of the characters.  Instead of me having to do all the work, how do I simply tell the AI to "change all the flesh-colored skin to snow white skin?" Or if need be, lime green, or charcoal black, or anything else.  I assume it would be handy for photographers as well to easily be able to change the skin of a person in any way they need, but without having to use sliders or brightness contrast, hue, or anything else, just BAM, done.
