Answer 1

Set the DatePicker so no weekend is selectable

$fieldsetDirector->addField(
        'attendance', 'date',
        [
        'name' => 'attendance',
        'label' => __('Attendance'),
        'title' => __('Attendance'),
        'date_format' => 'yyyy-MM-dd',
        'id' => 'attendance'
        ]
    )->setAfterElementHtml(
        '<script>
            require([
                 "jquery",
            ], function($){
                $(document).ready(function () {
                    $( "#attendance" ).datepicker({
                      beforeShowDay: $.datepicker.noWeekends
                    });
                });
              });
       </script>'
