Map ENABLED/DISABLED to enabled: true|false in a Schedule Event

Serverless Framework

I am migrating from CloudFormation to Serverless. In the old CloudFormation template I have a string parameter that toggles a EventBridge rule’s enablement:

Parameters:
    Param1:
        Default: ENABLED
        Type: String
        AllowedValues:
            - ENABLED
            - DISABLED
Resources:
    Rule1:
        Type: AWS::Events::Rule
        Properties:
            State: !Ref Param1

Now that I have moved to Serverless, I want to retain the Param1 parameter in the generated Cloudformation template so that my teammates control the enablement in the Cloudformation console:

serverless package --param "Param1=ENABLED"

    Param1:
        Default: ${param:Param1}
        Type: String
        AllowedValues:
            - ENABLED
            - DISABLED

but there is no way of mapping that value to the enablement in the serverless.yml file, because now we have a true/false value of enabled instead of a string value of State.

    events:
      - schedule:
          enabled: false # Cannot be mapped to ENABLED/DISABLED

What are the options we have?
