The S3 client enables this by default and then tries to read
.aws/config. This causes open_basedir restriction related error for
some setups. So this patch disables the CSM because it's most likely
unused anyway.

⚠️ Due to the lack of a local s3 system I did not test this patch ⚠️

Ref aws/aws-sdk-php#1659 (comment)

The S3 client enables this by default and then tries to read
`.aws/config`. This causes `open_basedir` restriction related error for
some setups. So this patch disables the CSM because it's most likely
unused anyway.

Code looks good, didn't test due to lack of S3 either.

Did some quick smoke test with minio and still seems to work without issues.

Code is good, but I'm using S3 as primary storage and I don't have open_basedir errors.

It seems that "false" is the default option value : https://github.com/aws/aws-sdk-php/blob/master/src/AwsClient.php#L74

When using S3 storage, we sometimes have open_basedir errors due to aws-sdk-php trying to read ~/.aws/config which is out of open_basedir restrictions.
Christoph Wurst already added csm=false config in #21406 but it wasn't enough, we also need to set use_arn_region=false, added in this commit.
