CentOS is a community maintained Linux distribution derived from the sources of Red Hat Enterprise Linux (RHEL). CentOS release versions follow closely RHEL releases, reusing the same version and release numbers. More information on the distribution releases and kernel versions can be found here.
Due to this design approach, CentOS zoned block device support is identical to that of Red Hat Enterprise Linux: zoned block device support is not available by default with the pre-compiled kernels shipped with the distribution.
However, third party repositories such as The Community Enterprise Linux Repository provide recent kernels packages precompiled with zoned block device suport enabled. elrepo provides kernels version 5.12 and 5.13 for CentOS 7, CentOS 8 and CentOS 8 STream.
