Is this the Calibre-default last-modified? It's honestly not a very accurate measure as stuff like running a Quality Check can change it. The plugin Last Modified with a custom datetime column is far more customizable.

But in this specific situation, yes, running single-field edits with Action Chains can modify it, both default and plugin. There's one exception:
