Procedural Seal boundaries not animable?


In the procedural meshing, I find interesting ina project that I’m doing to switch seal boundaries on and off.

When I double click the node for show the parameters it doesn’t appear, so I cannot put a math node (for example).

It’s this parameter not animable in anyway? I just to need to swith on off during performance.

kind Regards,
