    """<p>Modifies the default instance metadata service (IMDS) settings at the account level in the specified Amazon Web Services Region.</p> <note> <p>To remove a parameter's account-level default setting, specify <code>no-preference</code>. If an account-level setting is cleared with <code>no-preference</code>, then the instance launch considers the other instance metadata settings.

    Args:
        http_tokens: <p>Indicates whether IMDSv2 is required.</p> <ul> <li> <p> <code>optional</code> – IMDSv2 is optional, which means that you can use either IMDSv2 or IMDSv1.</p> </li> <li> <p> <code>required</code> – IMDSv2 is required, which means that IMDSv1 is disabled, and you must use IMDSv2.</p> </li> </ul>
        http_put_response_hop_limit: <p>The maximum number of hops that the metadata token can travel. To indicate no preference, specify <code>-1</code>.</p> <p>Possible values: Integers from <code>1</code> to <code>64</code>, and <code>-1</code> to indicate no preference</p>
        http_endpoint: <p>Enables or disables the IMDS endpoint on an instance. When disabled, the instance metadata can't be accessed.</p>
        instance_metadata_tags: <p>Enables or disables access to an instance's tags from the instance metadata. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/work-with-tags-in-IMDS.html">View tags for your EC2 instances using instance metadata</a> in the <i>Amazon EC2 User Guide</i>.</p>
        dry_run: <p>Checks whether you have the required permissions for the operation, without actually making the request, and provides an error response. If you have the required permissions, the error response is <code>DryRunOperation</code>. Otherwise, it is <code>UnauthorizedOperation</code>.</p>
        http_tokens_enforced: <p>Specifies whether to enforce the requirement of IMDSv2 on an instance at the time of launch. When enforcement is enabled, the instance can't launch unless IMDSv2 (<code>HttpTokens</code>) is set to <code>required</code>. For more information, see <a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-IMDS-new-instances.html#enforce-imdsv2-at-the-account-level">Enforce IMDSv2 at the account level</a> in the <i>Amazon EC2 User Guide</i>.</p>
