Can I assign/set an array of Vectors?

Unity Engine
1

Right now my shader has this

Properties {
    _HolePosition0 ("HolePosition0", Vector) = (0, 0, 0, 0)
    _HolePosition1 ("HolePosition1", Vector) = (0, 0, 0, 0)
    _HolePosition2 ("HolePosition2", Vector) = (0, 0, 0, 0)
    // ...
    _HolePosition9 ("HolePosition9", Vector) = (0, 0, 0, 0)
}

Is there a way to set an array of vectors in my shader? Or should I continue to hardcode N holes as the maximum number of holes allowed?

I did something similar but ended up using matrices instead - e.g.

float4x4 _HolePositions;

You can set those in the material in the c# code using SetMatrix. I’m not sure if that would be much different from using vectors though. If you’re having a lot of different holes it might be easier to create a texture with the hole positions encoded into the colour data and then you can decode it within the shader. That might be a bit slow though if you need to change the hole positions all the time.
