Yes. $19.99 narrow-wide MTB rings from SRAM. 1x setups just got a lot more affordable for 28t, 30t and 32t applications.

They are compatible with all SRAM 1x cranks (DM and 94BCD cranks) although the
DM 28-tooth ring is not compatible with 30mm cranks that require a 0mm offset ring and you must use SRAM chain to keep warranty.

That’s it. Plain and simple…
