How to prevent DRY in PHP. Refactoring task

class ManageableMapper extends BaseMapper
{
    public function map(array $data): array
    {
        return array_map(function ($row) {
            Arr::set(
                $row,
                'readonly',
                in_array($row['readonly'], config('User::user-management.roles.readonly'))
            );

            return $row;
        }, $data);
    }
}

and

class ManageableUserMapper extends BaseMapper
{
    /**
     * @param array $data
     *
     * @return array
     */
    public function map(array $data): array
    {
        return array_map(function ($row) {
            Arr::set(
                $row,
                'readonly',
                in_array($row['readonly'], config('User::user-management.roles.readonly')) || $row['super']
            );

            return $row;
        }, $data);
    }
}

Notice in this 2 classes the difference lies only in || $row['super']
