To trigger interpolation for LiveLink curve values above 0.1

Development Character & Animation
,
1

I am want to use LiveLink animation for the meta human, but I trying to exaggerate eyebrow furrowing in the meta human.
So, whenever there is LiveLink input for BrowDownL and BrowDownR of over 0.1, I want the output to be an interpolation from that value to 1 (the maximum eyebrow furrow).

Does anyone have any idea how I can do this?

Thank you
