At the moment, your best bet is to extrude the curve in question, cap it, and do a boolean subtraction. There are more options available if you are open to scripting.

could you give me some hints on how to approach this through scriptable component?

Convert your OnSurface to OnBrep through OnSurface.BrepForm, or just set your type hint to OnBrep. Then use:

RhUtil.RhinoBrepSplit

This is not always very reliable.. in that it splits the Brep, but still returns only a single brep with the faces split at the curve in question.

If that does happen, you could use the explode component, or extract the faces from OnBrepFaceArray.
