I have trouble with processing sky and ground, and usually I resort to lots of manipulation. I’d like to keep it within a RAW editor, so exactly how I can process these separately. Making the mask to separate the two in a external software isn’t difficult, so I’d be fine with two different setups.
For now, I’m using Darktable. So, that would be preferable, but I’d be fine with other approaches too.
Can you share an image?
It’s more of a general topic, but here’s a test image in question:

Yes, I’m aware of the vignette.
I did a quick and dirty one at the tree line and then just messed around…
The mask should be easy enough to make for that image (as @difrkaguilar has shown), if dt has a levels Threshold function like in the GIMP.
Difficulty appears when the levels in the sky are not sufficiently distinct from the ground - and perhaps we should concentrate on that aspect rather than stating the obvious re: masking.
I think that would be the parametric mask on either the g or Jz channel to set and feather the threshold if I understand what you are saying
There was actually a new video today that does a nice job of demonstrating landscape masking
