Modify a vector 2 in pbr shader using c#

Hi there, I’m trying to modify a vector 2 property in my shader, how can I access it from script?
I can’t use material.SetFloat because that only wants one value, unless there’s a way to access the single x or y value?

I’m like Dora over here. The way to do this is to use a combine node to generate a vector 2 from two vector 1s. Yay!
