Can chronic dehydration cause chronic hives (physical urticaria) since water directly affects histamine production in the blood? Rehydration cure it?

In brief: No.

dehydration is not a standard cause of hives.
Of course it certainly is easy enough to find out. Frankly, NEURODERMATITIS https://www.aad.org/dermatology-a-to-z/diseases-and-treatments/m---p/neurodermatitis/who-gets-causes is more common than association with dehydration.
