Doorbell Elite adapter for mounting to brick?

Is there a special (UK, European?) adapter for the Elite, for use on brickwork? The US arrangement seems to need a very large and deep hole for the orange adapter. Or is it OK to discard the adapter and screw the Elite itself direct to the bricks? Or make a pattress? That way, I need only drill a small hole for the cables through to the cavity behind the brickwork. Grateful for any guidance, please.
