Laravel DB::query to eloquent

Hello,

I've the follow DB query, but, I want to convert to Eloquent to use "with" statement for some childs and use in master/detail grid. It's possible ?

I've tried some ideas, without success.

$items = DB::table('pessoa_fisica as pf')
            ->join('atend as a', 'a.pefi_id', '=', 'pf.pefi_id')
            ->join('atend_servico as ateser', 'ateser.atend_id', '=', 'a.atend_id')
            ->join('servico as s', 'ateser.servico_id', '=', 's.servico_id')
            ->join('convenio as c', 'a.convenio_id', '=', 'c.convenio_id')
            ->join('atend_agendado_servico as aas', 'aas.ateser_id', '=', 'ateser.ateser_id')
            ->leftjoin('tratamento_servico_atend as tsa', 'ateser.ateser_id', '=', 'tsa.ateser_id')
            ->leftjoin('tratamento_servico as ts', 'tsa.traser_id', '=', 'ts.traser_id')
            ->select( 's.descr as descr_servico'
                    , 'c.descr as descr_convenio'
                    , 'ts.dt_alta'
                    , 'pf.nome'
                    , 'pf.num_cliente'
                    , 'pf.pefi_id'
                    , 's.servico_id'
                    , \DB::raw("date_format(aas.dt_agendada_ini, '%H:%i') as hr_agendada")
                    , \DB::raw("date_format(aas.dt_agendada_ini, '%w') as dia_semana_agendada")
                    , \DB::raw('count(*) as total_consultas')
                    )
            ->groupBy(\DB::raw("s.descr
                              , c.descr
                              , ts.dt_alta
                              , date_format(aas.dt_agendada_ini, '%w')
                              , date_format(aas.dt_agendada_ini, '%H:%i')
                              , pf.nome
                              , pf.num_cliente
                              , pf.pefi_id
                              , s.servico_id
                              "))
            ->whereRaw('aas.status = 1')
            ->whereRaw('pf.num_cliente = 107014')
            ->orderBy(\DB::raw("s.descr, count(*)"))
            ->havingRaw("count(*) > ?", [ 3])
            ->paginate(50);


          $response = [ $items,
                        'links' => [
                              'pagination' => [
                                  'total'         => $items->total(),
                                  'per_page'      => $items->perPage(),
                                  'current_page'  => $items->currentPage(),
                                  'last_page'     => $items->lastPage(),
                                  'from'          => $items->firstItem(),
                                  'to'            => $items->lastItem()
                              ],
                          ]
                      ];
