4. Create Assets > right-click > Shader > PBR Graph
5. Create new node from New Shader Graph window > PBR Master > Vertex Position > Artistic > Adjustment > Channel Mixer
6. Select Shader Graph window > Channel Mixer > right-click > Convert To SubGraph
7. Double Click on Project > Assets > New Shader Sub Graph > New Shader Sub Graph window > Save Assets

Expected Result:
