How to do UPDATE 1 to 1, with four tables in laravel

I'm working with a database already populated. It has four tables (Student, Clinical, Family, and Compulsory Type), where Student receives foreignkey from the three tables;

Model Student

class Aluno extends Model{


    public $timestamps = false;
    protected $fillable =[
                        'Nome','Sobrenome','Cpf','Email','Altura','Telefone','Endereco'
    ];

    public function clinico(){


        return $this->belongsTo(Clinico::class);
    }
    public function familia()
    {
        return $this->belongsTo(Familia::class);
    }
     public function tipocompulsao()
    {
        return $this->belongsTo(Tipocompulsao::class, );

Clinical model

class Clinico extends Model
{
    public $timestamps = false;
    protected $fillable=[
        'hasAnsiedade',
    'hasInsonia',
    'hasHipertensao',
        'hasDiabetes', 
    'hasAlergias', 
    'hasDisturbiosOncologicos',
    'hasProblemasRenais', 
        'hasMenopausa', 
    'hasHipotiroidismo',
    'hasColesterol', 
    'hasFigado', 
    'hasOutros' 
    ];

    public function aluno() {
          return $this->hasOne(Aluno::class );

      }
}

model family

 class Familia extends Model
{
      public $timestamps = false;
      protected $fillable=[

         'hasObesidade',
    'hasDoencaRenal',
        'hasHipertensao', 
        'hasColesterolGorduraFigado'  

      ];
      public function aluno() {
          return $this->hasone(Aluno::class);

      }
}

Tipocompulsao

    class Tipocompulsao extends Model{

      public $timestamps = false;
      protected $fillable=[
        'hasCompulsaoDoce',
    'hasCompulsaoSalgado'  
      ];

      public function aluno() {
          return $this->hasone(Aluno::class);

      }
}

Controller to save dataform

public function update(Request $request,$id)
{


    $tipoco=Tipocompulsao::update($dataform);
    $clinico= Clinico::update($dataform);
    $familia=Familia::update($dataform);
    $aluno=Aluno::update ($dataformU)->where($id);


    $aluno->familia()->associate($familia);
    $aluno->clinico()->associate($clinico);
    $aluno->tipocompulsao()->associate($tipoco);
    $aluno->save();

The main problem I wanted to solve is: how to do UPDATE on tables with 1 to 1 relationship?
