AWS S3 intelligent tiering enabled or not

hello, I want to verify a configuration on few buckets that I am seeing.

1. Does below output mean that intelligent tiering is configured on the bucket and that objects will transition between tiers? I am not seeing the other tiers in this output which I think is because the other three are default.
2. Is it possible to only have enable default tiers and not the archive and deep archive?

aws s3api get-bucket-intelligent-tiering-configuration --bucket samplebucketname --id lifecyle-tier
{
    "IntelligentTieringConfiguration": {
        "Id": "lifecyle-tier",
        "Status": "Enabled",
        "Tierings": [
            {
                "Days": 90,
                "AccessTier": "ARCHIVE_ACCESS"
            },
            {
                "Days": 180,
                "AccessTier": "DEEP_ARCHIVE_ACCESS"
            }
        ]
    }
}
