Different ARN role usage in the EKS POD (which has service account defined with another ARN role)

I am starting the pod with a ARN role coming from Service Account, now i need to use different ARN role get the access to a different AWS resource. how can i get the credentials provider with a different ARN role other than the one coming from Service Account.

The issue names no files, tests, or entry points. First clarify whether the webhook is expected to support credentials for a second ARN role and identify the relevant EKS pod identity flow; done would require a documented, supported way to access the different AWS resource.
