VDO was a service in RHEL 8 (we taught it that way). Here's my slide for this (again RHEL 8 not 9):
It doesn't appear to be a service in RHEL 9; there is no vdo.service unit file. Instead, it has become an option that is used with LVM. For example:

I have not ever used or tried VDO before.
Is there an actual service that needs to run? The documentation for RHEL 8 and 9 suggests that there is not -> https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/deduplicating_and_comp...

Hi Tracy,
I had VDO volumes created on an old machine, how do I import these on RHEL 9, I tried lvm_import_vdo, it is still requesting vdo command to be present ?
lvm_import_vdo --dry-run /dev/nvme0n1
lvm_import_vdo: Checked whether device "/dev/nvme0n1" is already logical volume.
lvm_import_vdo: Getting YAML VDO configuration.
/usr/sbin/lvm_import_vdo: line 593: vdo: command not found

Yes you are right, starting RHEL 9 VDO is now part of LVM. You can refer to this documentation explaining use of VDO on RHEL 9
