Yeah higher protein diets should cause more frequent urination, it’s not just the extra water. I know that certain proteins are in the kidney (Na/K ATP-ase, Na-glucose transporter, Aqauporins) which are a integral to the re-absorption that occurs in the kidney, from the proximal tubule to blood vessel/capillaries near it.
Aquaporins particularly allow water to flow easily across the cell membrane, so I’m guessing the extra protein we take in means more aquaporins?
I feel you may be overanalyzing, an unavoidable metabolite of a high protein intake - urea - is a diuretic.

Probably… I just learned the stuff in Bio so it was fresh in my mind
