It’s an OOTB node from a further release than you are in.

so OOTB means “Out Of The Box” Node - how do i deal with that? who is Jeeves?
Yes - OOTB means out of the box, means it’s a part of Dynamo Core.
To get this node you will have to upgrade to a newer version of Dynamo. Dynamo 2.3 should have the node, which means from a Revit perspective you will need Revit 2020.2 or newer. If you are in a mixed environment (not recommended) you will need to upgrade to 2020.2 to use a graph that leverages this node.
oh… the problem is i use Revit 2018.3.3. with 2.0.4. Dynamo
can i just copy this node?
Nope. There are a multitude of work-arounds though.

Surface.TrimWithEdgeLoops:
