Can you use self-managed S3 server as prefect storage?

Bucket name must match the regex "^[a-zA-Z0-9.\-_]{1,255}$" or be an ARN matching the regex "^arn:(aws).*:(s3|s3-object-lambda):[a-z\-0-9]*:[0-9]{12}:accesspoint[/:][a-zA-Z0-9\-.]{1,63}$|^arn:(aws).*:s3-outposts:[a-z\-0-9]+:[0-9]{12}:outpost[/:][a-zA-Z0-9\-]{1,63}[/:]accesspoint[/:][a-zA-Z0-9\-]{1,63}$"

@Kevin Kho Thanks. I have successfully created a FileStorageBlock using our own S3 server for a deployment. Any way I can create this storage as default?

I think not at this time but there is work being done to make S3 Storage compatible with self hosted
