Upload artifacts without Updating Stack

Is there a way to upload CloudFormation file, artifacts and services to S3 without Updating the Stack ?

I would like to use the cloudformation deployment of AWS CodePipeline to be able to cross account deployments.

Based on the reference architecture for SAM : https://github.com/awslabs/aws-refarch-cross-account-pipeline

I was able to setup the CodeBuild project and CodePipeline App using serverless.
I would like on package that the “Code” property value is “./handler.zip” in place of the S3 bucket and key.
This will let you run the aws cloudformation package command as here : https://github.com/awslabs/aws-refarch-cross-account-pipeline/blob/master/ToolsAcct/code-pipeline.yaml#L119
and specify the package folder as artifact in the buildspec.yml file
