In Gitlab Pipeline how to add another condition in the same rule using reference

Question

In gitlab pipeline I have a job with rule using "reference". How do I add another condition in the same rule using

.rules:default:
  rules:
    - if: $CI_PIPELINE_SOURCE == 'merge_request_event'
      when: never
    - if: $CI_COMMIT_REF_NAME == "main" && $VERSION_NUMBER != "current"

myjob:
  stage: myjob
  script:
    - echo "I am executing myjob"
  rules:    
    - $Environment == "sbx" && !reference [".rules:default", rules]

this show this as error This GitLab CI configuration is invalid: jobs:myjob rules should be an array containing hashes and arrays of hashes

You can't do string interpolations with !reference -- there are no interpolation primitives in the YAML spec, either.

However, you can get a the same effect you want by using an additional rule instead:

  rules:    
    - if: $Environment != "sbx"
      when: never
    - !reference [".rules:default", rules]
