Hi Sudhakar Battula,
I did not find a Qlik Branch extension doing what you want to achieve, but this thread may lead you in the right direction: https://community.qlik.com/thread/158784
Hope this helps,
As per your query, my suggestion will be to create a reload button in the main qvf file. In QMC, you have to assign trigger task to reload other qvf files.
For manually testing you can try using POSTMAN APP.
