[mimir-distributed] What style of accessing the S3 bucket is used in mimir distributed?

[arsbest]

Hello!

What style of accessing the S3 bucket is used in mimir distributed?
I couldn't find the S3 access style (path-style or virtual hosted style) settings options in the storage configuration https://grafana.com/docs/mimir/latest/references/configuration-parameters/#s3_storage_backend , https://github.com/grafana/mimir/blob/main/operations/helm/charts/mimir-distributed/values.yaml

What is the default style?
