Summary

• Pin the NVIDIA driver role to v2.4.0, now available from Ansible Galaxy.
• Align Ubuntu open-kernel package selection's pre-role fallback with the role's driver branch 580 default, preserving explicit branch and suffix overrides.
• Document matching kernel-modules packages for offline EL9+ distribution mirrors and the option for separately managed modules.
• Add a fact-only package-selection regression covering default open modules, explicit branch overrides, suffix overrides and unchanged proprietary configurations.

Validation

• Fresh isolated ansible-galaxy role install nvidia.nvidia_driver,v2.4.0 succeeded.
• Five local package-selection cases passed in normal and check mode; the default-open case failed before the fallback fix.
• Driver playbook syntax check passed with the installed v2.4.0 role.
• Diff whitespace and public-content checks passed.
• Independent review passed on this exact commit.

Notes
