Physics.Raycast has a parameter named layerMask. It will help you to eliminate the layer on which you do not want raycast.

   // Bit shift the index of the layer (8) to get a bit mask
    int layerMask = 1 << 8;

    // This would cast rays only against colliders in layer 8.
    // But instead we want to collide against everything except layer 8. The ~ operator does this, it inverts a bitmask.
    layerMask = ~layerMask;
