Importing Fedora CoreOS VMDK into AWS

[Promaethius]

I've run into a situation where I need to import Fedora CoreOS into ec2 as a custom ami. After downloading, unzipping, and uploading into S3, I get this error.

{
    "ImportImageTasks": [
        {
            "ImportTaskId": "import-ami-...",
            "SnapshotDetails": [
                {
                    "DiskImageSize": 733499904.0,
                    "Format": "VMDK",
                    "Status": "completed",
                    "UserBucket": {
                        "S3Bucket": "...",
                        "S3Key": "fedora-coreos-31.20200210.3.0-aws.x86_64.vmdk"
                    }
                }
            ],
            "Status": "deleted",
            "StatusMessage": "ClientError: EFI partition detected. UEFI booting is not supported in EC2.",
            "Tags": []
        }
    ]
}

I'm using the cloud operator aws version.
