please tell me, is it possible to do something so that you can indicate some other s3 sources, host and providers other than s3.amazonaws.com ?

so as not to be hard-coded

upd2: what the hell , why are you confusing the host with the bucket,?
And this is with a URL starting with s3://

upd: None

def _get_fixed_url(url: Optional[str]) -> Optional[str]:
        if not (url and url.lower().startswith("s3://")):
            return url
        try:
            fixed = furl(url)
            fixed.scheme = "https"
            fixed.host += ".s3.amazonaws.com"
            return fixed.url
        except Exception as ex:
            print(f"Failed processing link {url}. " + str(ex))
            return url
