Hi visuall,
it depends on what you need at the end.
You can render without Alpha channel and obtain the alpha mask by enabling the Render Layer Mask pass:

beauty

Render Layer Mask

Or render with Alpha channel active and add a white layer behind the beauty pass:

beauty

beauty with alpha

beauty + white layer
