dnf --showduplicates list satellite sudo dnf downgrade satellite-<VERSION_BEFORE_6.4> sudo dnf versionlock add satellite

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
