Composite action should not download other actions if they are disabled

[motatoes]

can the downloads of action be limited based on the inputs received ?

workflow file has a setup-aws=true and the associated env vars. I understand the actions/* ones and the terraform ones.

Would really like to see this feature to reduce the time of runner and reduce external dependencies coming in for more regulated environments.

I don't think GitHub Actions has any way to achieve this.

The dependent actions are resolved and downloaded before execution (as seen by the timing of the download logs), and step conditionals can use data generated at runtime (e.g. the output of an upstream step), so there is no way of knowing a priori if a dependent action will be needed or not.

If GHA supported lazy loading of actions it would be possible but that is not the case.
