Probably. But, as
HTupolev said, there isn't much of a market for rim brakes anymore*. Based on the vast majority of bikes that are still being sold with that braking option, if you found one, expect the frame and wheel-set to be heavy and possibly a poor geometry for your intended use, and the components to be lower quality, and potentially the gearing to be 8- or 9-speed. To get a good quality bike (modern frame), optimized for gravel (proper frame geometry), with good components, you'd probably be best off to build it.
*Plenty of discussions with lots of uninformed and conspiratorial ideas about why this is in other threads.
