WD was pushing for this standard a few years back: https://www.westerndigital.com/company/innovation/zoned-stor... I'm not sure what happened to it / whether it was successful or not.
I think they also sold HA-SMR (host aware SMR, a mix of drive managed and host managed) drives to datacenters but I couldn't find any recent news so I guess those aren't that common.
