(Help) Use existing role instead of creating new roles

,

I am using a restricted AWS account. Which has two roles:

  1. IAM (Allows all IAM permissions)
  2. Devops (Allows all permission except IAM Role creation)

Currently sls deploy is trying to create two roles:

  1. IamRoleCustomResourcesLambdaExecution
  2. IamRoleLambdaExecution

I have removed the first role creation after defining role parameter in each functions.
Second role is getting created for s3 events to lambda execution.

Is there a way I can disable this role creation and manually create this role?
