You could try talking to your fabricator and telling them that you
don't want the solder mask, and also remove the mask layer(s) from the
generated gerbers before sending them out. While different fabricators
offer a different degree of service, I expect most fabricators will be
able to handle this kind of simple instruction, i.e., completely
eliminating a layer,  without too much trouble.

In the past I've been able to get my fabricator to add certain simple
features which PCB doesn't support, including things like rectangular
plated slots for bus bars and alignment drills on stencils. Such
specific instructions do take some explaining, though, and a fairly
sustained back and forth before they understand what exactly you need.
Selection of layers and changing layer ordering on multi-layer boards
is a much easier instruction to give and is easily and commonly
understood.
