Can I use an image texture to delete verts?

I am using displacement modifier on a plane to generate a shape from a black and white image. I use the same image to make the flat outside area of the plane transparent. I would like to completely delete the flat areas as defined by the texture. Is there any way to use a texture with the Mask Modifier to delete verts?

In 3.0 alpha, you can use geometry nodes to delete geometry:

Thanks. This works. It just isn’t working with my particular image as expected.
