Magento 2 Custom Admin tab grid content based on the selected form values

In my requirement, I need to load the tab grid content based on the first tab form selected values.

It’s third party module i am going to override, in that the first tab form loaded based on $fieldset and the second tab grid content loading based on the addColumn.

So, now i am going to introduce a new tab, which has some drop-down values, based on that dropdown values i need to filter the grid content.

Your suggestion and ideas will be much help to moveforwards
Thanks in advance for your better support.
