Update Texture set on Geometry Node

hi ,

i have set a texture on a geometry node with the following low level call
node.setGeomState(0, node.getGeomState(0).addAttrib(TextureAttrib.make(Tex ) ) )

usually with the high level interface one would use the over ride flag when calling setTexture to update the texture , how is this achieved on the low level interface?

Use:

stage = TextureStage.getDefault()
attr = TextureAttrib.make().addOnStage(stage, tex, override=123)
