VM instance identity like AWS one

Does openstack provides a VM specific instance identity? For example a VM running in AWS can retrieve a specific identity using the service decribed at: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-identity-documents.html (https://docs.aws.amazon.com/AWSEC2/la...)

Openstack assigns to a VM a unique ID, but I'm wondering if there is any signed token/identity the VM can use to demonstrate that is really has that ID assigned to it.

My use case is the following: I would like to "assign" some secrets to a specific VM and have the VM authenticate to the secret store with some Openstack provided identity that I can check with Openstack before releasing the secrets.

I found that this is possible through vendor-metadata (https://docs.openstack.org/nova/latest/admin/vendordata.html (https://docs.openstack.org/nova/lates...)).
