You could apply local contrast or equalizer with 'darken' merge mode to avoid blowing out highlights; you can even use multiple instances and add parametric masks so you use 'normal' merge mode for midtones, and 'darken' for highlights. Posting the NEFs would allow us to play with them. I'd start w

Hi! Clouds tend to be in the upper part of an image and there is usually a pretty obvious intensity distribution from "really high" in the clouds to "rather low" at the bottom. So I usually just apply a vertical linear intensity gradient to get the heaven down to levels where you can discriminate
