Just deploy cloudformation changes for AWS

I am making changes just to custom resources in my serverless.yml with an AWS provider. The package from the lambda code is not changing, it’s already uploaded to S3 from a previous deploy.

How can I say “use the artifacts already in S3, just upload the changed cloudformation template and update the stack using that”?

Hello and welcome,
If the name of the serverless package is not changed (the service name) if you do any change to the serverless file and run sls deploy, the changes will be made on the same resources.
