There exist "host-managed SMR" drives. In the SCSI/SAS specifications, these use the "Zoned Block Devices" command set, rather than the SCSI Block Commands (SBC) command set. As far as I can tell it's seemingly impossible for an individual to buy host-managed SMR (ZBC) drives. Presumably they're only sold in bulk to datacentres. Maybe that could change if some demand materialised and was communicated to a suitable retailer...
