It seems you are seeing self shadowing. Basically the high resolution mesh self shadowing the Nanite mesh or vice versa. This will happen if you are suing RT shadows as RT shadows use the high resolution mesh. try switching to Virtual Shadow Maps or If you have to use RT shadows, in the Nanite mesh settings change the “Fallback Relative Error to 0” see if this helps.
