No, but you can set env variables from your wp-config.php:
putenv(“ILAB_AWS_S3_BUCKET=my-wp-bucket”);
putenv(“ILAB_AWS_S3_ACCESS_KEY=56NMA…KIAGUBA”);
putenv(“ILAB_AWS_S3_ACCESS_SECRET=pW5nI1s…jsoMwFq”);
putenv(“ILAB_AWS_S3_REGION=eu-central-1”);
And leave the fields empty in the storage settings page
