sram 11 speed mtb cassettes for XD driver have a 10 tooth cog as the smallest. not sure if that actually answers the question you are asking though…

3T Made some for their 1x11 road experiment. Should still be available.

The Bailout and Overdrive cassettes go all the way down to a 9t cog: https://us.3t.bike/en/products/drivetrain/cassette-579.html
