Hello everyone, Has anyone attempted accessing a public s3 bucket using the S3 block or know of a work around? Had a good search around but can't seem to find how you could change the S3 validation.

The credentials on the block are optional so this should work. You may also check the blocks from the prefect-aws collection - there are blocks there like S3Bucket https://github.com/PrefectHQ/prefect-aws/blob/main/prefect_aws/s3.py#L232 or you can do:

import fsspec

fs = fsspec.filesystem("s3")
fs.put("/Users/anna/repos/dataflow-ops/docs", "<s3://prefect-orion/docs>", recursive=True)
