using Gitlab CI workflow and Gitlab CI rules make what i want to do.

image: ...

workflow:
  rules:
    - if: '$CI_COMMIT_BRANCH' # All branches
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' # Merge requests
    - if: '$CI_COMMIT_BRANCH && $CI_OPEN_MERGE_REQUESTS' # Fix detached merge request pipelines
      when: never

When working with merge requests, you need to use workflow and rule to control how the runner should trigger the pipelines. You can read more about them on Gitlab's official documentation: Gitab CI workflow and Gitlab CI rules

Using workflow, you can control the execution of stages generally, and using rules you can control the execution of a specific stage. You can use Predefined Variables or even custom variables to write some rules.

For instance, in the following sample, the runner will trigger the pipeline if there is a push over branches and when a merge request is created. It will also disable branch pipeline when you push to a branch when there is an open merge request.

image: ...

workflow:
  rules:
    - if: '$CI_COMMIT_BRANCH' # All branches
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event"' # Merge requests
    - if: '$CI_COMMIT_BRANCH && $CI_OPEN_MERGE_REQUESTS' # Fix detached merge request pipelines
      when: never

And in the following example, you can limit the execution of a stage by the name of the source and destination branches in the merge request.

job:
  script: echo "Hello, Rules!"
  rules:
    - if: '$CI_MERGE_REQUEST_SOURCE_BRANCH_NAME =~ /^feature/ && $CI_MERGE_REQUEST_TARGET_BRANCH_NAME == $CI_DEFAULT_BRANCH'
      when: always
    - if: '$CI_MERGE_REQUEST_SOURCE_BRANCH_NAME =~ /^feature/'
      when: manual
      allow_failure: true
