I did it with a option in SubTree node (see attachment).

It seems to work well and its a few lines of code:
Add this in SubTree:
[SerializeField]private bool _initOnGraphStart = true;

1 2 3 4

public override void OnGraphStarted(){ if (_initOnGraphStart) CheckInstance(); }

And this in OnNodeInspectorGUI method:
_initOnGraphStart = EditorGUILayout.Toggle("Init On Start", _initOnGraphStart);
