Possible to clear animation on a single parameters?

dudeness

Hello! I’d like to know if it is possible to clear a single parameter easily from say, a specific body part?

For example, within the "head", there are lips / eye lids / etc and instead of clear animation of the whole head, I only want to clear the eye’s animation. 

In the "paramters setting" i can see which keys have been assigned as keyframes. But manually changing them to zero over there does not seems to save..

Any tips will be appreciated!
