Hi Aditya Singh,
Thanks for using Microsoft Q&A!!
I am afraid it is not possible as the pipelines which you want to use while configuring a pipeline run needs to be from a published pipeline in Azure Data Factory of the respective data factory and thus you are only able to see the pipeline which are published (Live mode) in ADF.
Please feel free to provide your feedback with your use case on Azure Feedback portal so that community can upvote and products team could take up this requirement in any future releases.
Please let me know if you have any other questions.
Thanks
Saurabh
