@Rajani : This is what I am doing. I am having git actions to kick off which will run 

- name: bundle-deploy
run: |
      cd ${{ vars.HOME }}/dev-ops/databricks_cicd_deployment
      databricks bundle deploy --debug

Before running this step, I am creating the yaml file of the modified/newly created workflow alone under resource directory of DABs folder setup. Once I execute the above command it will remove all the other workflows which is not available under resource folder path in the target server.
