yes, dnf supports wildcards and I did a quick test on rocky9 to confirm:

Hi folks, as you also noticed the discussion with Matt, we could use a wilder scope of 5.x here to install the podman 5 latest version. As of writing, 5.4, result is the same, but the new command is more aligned to what we support.

Details in below comment:

* To prevent automatic Podman updates to unsupported versions, configure the Podman version to be locked at version `5.4.*`.

```sh

sudo dnf versionlock add --raw 'podman-remote-5.2.2'

## Verify that podman-5.2.2 and podman-remote-5.2.2 appear in the output
## Verify that podman-5.4.* and podman-remote-5.4.* appear in the output
sudo dnf versionlock list

* **Grow-and-shrink upgrade**: [Add new hosts](./install-ece-on-additional-hosts.md) running the desired Podman version to your ECE installation, then [remove the old ones](/deploy-manage/uninstall/uninstall-elastic-cloud-enterprise.md). This method is safer and preferred, as it avoids potential risks associated with upgrading the container engine or the operating system in place.

ECE only supports Podman 5 in version `5.2.2`, regardless of your upgrade method. Later versions such as `5.2.3` and above are not supported. Refer always to the official [Support matrix](https://www.elastic.co/support/matrix#elastic-cloud-enterprise) for details on supported versions.
