It takes 2...
You've gotten feedback from multiple people that your proposal is not
going to be accepted. The prior attempt of the same thing had similar
feedback from even more people. Please go re-read the responses until
you understand.
For fixed-regulator, I can tell you very easily what the h/w looks like:
Vfix---|gate|---Vfix-gated
|
GPIO--------|
'gate' here may be a chip or discrete transistor. That's a very common
board level component.
If you want to discuss this any further, describe the h/w in terms of
simplified schematics. Otherwise, there is nothing more to discuss.
