Find users in a group having a role in another group

In my organization, roles are used to describe a user job. For instance I could have an IT role in /acme.

Now I am trying to find all the users in the HR Group (I have its id) that have a given role in /acme

Is there a way to build such a query using SearchOptionsBuilder or should I iterate over the users in HR Group to apply my second filter?

If not... well that would be a nice addition!
