Just figured out the solution to this myself so I share it here
$nfl_question_repeater = get_field('nl_form_questions', 'options' );
//Just change the number here to specify the first repeater row
$row_outer = $nfl_question_repeater[0];
$row_question = $row_outer['question'];
//Just change the number here to specify the nested repeater row
$row_inner = $row_question[1];
$row_inner_value = $row_inner['uses'];
