Hello @alexandergiss .
This action is not for building Qt, but downloading and installing the pre-built Qt stuff with aqtinstall. So I think you may have to build Qt with custom options in GitHub Actions' environment by yourself.
In addition, there is cache mechanism in GitHub Actions to speed up your workflows (Caching dependencies to speed up workflows - GitHub Docs). And, you could try to download Qt's source code with help from aqtinstall (list-src-command § Command Line Options — aqtinstall 3 documentation).

Yes, this action is only able to do what aqtinstall is able to do.
