About ModifyInstanceMetadataDefaults

Modifies the default instance metadata service (IMDS) settings at the account level in the specified Amazon Web Services
 Region.

To remove a parameter's account-level default setting, specify no-preference. If an account-level setting is cleared with no-preference, then the instance launch considers the other instance metadata settings. For more information, see Order of precedence for instance metadata options in the Amazon EC2 User Guide.
