Set Float Curve Key to Variable Value

Is there any way that I can set one of the point’s value on a float curve to equal that of a variable? If your not sure what I am talking about, a float curve is the graph thing you can make, and retrieve values at certain time’s from it. Any help is appreciated!

Bumping due to no replies in a week. Hope someone can help me out.

If you make the curve between 0 and 1 you can drive a lerp to scale your curve.

I am also interested in how this works or if this is possible at all.

How I add or set keys of float curve variables via blueprint nodes in a blueprint?
