Hello, the Clip function should be accessible through the node list in any of the Shader Types, is it not present on your side?
If not, which ASE version are you on? Please make sure that you're using the
latest build from our website.
If you're using a Standard shader, you don't need this node since the alpha clip is already incorporated in the Opacity Mask, which you can access by setting the shader's Blend Mode to Masked.
If you're using a Template, it should be added at the end of the instructions like in the example shown in its wiki page.
I believe that this is the only way to reduce overdraw.
