Unity shader. To transfer each variable, or one global?

Question

C++ / C#

Hello comrades, the question is to those who know, who studied this issue, gained experience.
Question for mobile devices.
Let's say there are 2-3 shaders, let's say they work depending on the weather in the game. Good / bad.
What is the best way to pass the SetInt weather value to everyone? Or pass the global value through Shader.SetGlobalInt(...) ?
So the question is, how much worse is Shader.SetGlobalInt? Or no difference in load at all?

I would prefer a global variable
