If you count Linux, sure, Linux for the S/390 and zSeries.
If you don’t…well, for one brief shining moment before IBM squeezed too hard on the price

support 3390 type devices.
I may have had something to do with that latter device driver.

Except on the RX’s. The RX01 was 128 byte sectors and the later ones 256
and a odd interleaving strategy. However, the boot block and the rest of
the file systems (both UNIX and RT at least)
just aggregated the smaller (logical) sectors together to make a 512 byte
one.
At least they all supported fixed-length sectors. Was there ever a
Unix implementation that supported IBM-style CKD disk devices?
