Hi Anshal,
Thanks for reaching out to Microsoft Q&A.
There is a nice article by Koen Verbeeck which points out the very precise and clear options that are available in ADF when it comes to saving costs. I strongly suggest you to have a look at this as I benefitted something out of this article w.r.t ADF cost cutting.

And as always you can use the budgets/alerts that are available in the azure to manage your adf costs effectively.
