Accepted Answer

You can do that by delegate access across AWS accounts using IAM roles.
Use AWS Mgmt Console to establish trust between the Mgmt and Vendor account. Create a IAM role named e.g. vendorARole. When you create the role, you define the Vendor account as a trusted entity and specify a permission policy that allows trusted users to access only one of the EC2 instance via tagging.
