IMDSv2 uses token-backed sessions. Set the use of HTTP tokens to optional
(in other words, set the use of IMDSv2 to optional) or
required (in other words, set the use of IMDSv2 to
required).
optional - When IMDSv2 is optional, you can choose to retrieve instance metadata with or without
a session token in your request. If you retrieve the IAM role credentials
without a token, the IMDSv1 role credentials are returned. If you retrieve the IAM role credentials
using a valid session token, the IMDSv2 role credentials are returned.
required - When IMDSv2 is required, you must send a session token
with any instance metadata retrieval requests. In this state, retrieving the IAM role
credentials always returns IMDSv2 credentials; IMDSv1 credentials are not available.
Default: optional
Set to enabled to allow access to instance tags from the instance

Default: disabled
The metadata options for the instance. For more information, see Instance metadata and user data in the Amazon Elastic Compute Cloud User Guide.
