Is there a way to use grouping settings for Bootstrap Tabs in Views?
There isn't a way at the moment to use the built in views group by function, but luckily there is a way to accomplish similar behavior if you install a contrib module called views field view.  

https://www.drupal.org/project/views_field_view

The premise being, tabs separate a listing of entities into multiple groups based on a common term.

Not like this: https://monosnap.com/file/K4W6m63A1jsy7frYdL8P0LfcFQPj29

But like this: https://monosnap.com/file/Q8WsRSgJU7f8AYFMMomDmcIjyOAXZE

In order to make this work, you need two views, One with the tab output, and another contextually filtered as a field within the first.

View 1 (list of taxonomy terms) would look like this to create the labels for the tabs: https://monosnap.com/file/h3fDlfgy2HwlHT2Y3Lywe8IroagDyE

View 2 (Use a relationship to call the nodes that are referencing each term and a contexual filter to limit the nodes per term id): The view field here is the key: https://monosnap.com/file/NtIumKYmsws62o4kTAnU72mt1LPZZq

Once you have the two views you can set the argument on view 1
