Use the s3 source connector to read data from on-prem s3 bucket

Hi Team,

I want to use the Aiven S3 connector to connect with an on-prem S3 bucket.
The current APIs seem designed only for AWS S3, I want to check if it is possible to connect with on-prem s3.
If so, is there an example configuration which shows the connection attributes for on-prem?

Thanks.
