Hi @Anonymous ,
It is not possible to directly connect to AWS S3 without Power BI Desktop. There are two methods for you connecting to the data source.
1. Connect to AWS S3 using ODBC data source as described in this blog or directly call AWS S3 api in Power BI web connector. Create report in Power BI Desktop and publish it to Power BI Service.
2.Create Power BI service content pack following the guide in this article, Power BI Desktop is also required.
I have also found a similar post, please refer to it to see if it helps you.
