Unique rule with MorphToSelect fields

Hi ! I'm trying to create a form for a "relations" polymorphic table I have in my database to manage relations between three entities (Users, Companies and Institutions). Here is the table code :

  Schema::create(self::TABLE_NAME, function (Blueprint $table): void {
      $table->id();
      $table->bigInteger('relationable_id')->unsigned();
      $table->string('relationable_type');
      $table->bigInteger('target_id')->unsigned();
      $table->string('target_type');
      $table->string('relation_type', 45);
      $table->timestamps();
      $table->index('relation_type');
      $table->unique(['relationable_id', 'relationable_type', 'target_type', 'relation_type'], self::TABLE_NAME . '_unique');
  });

  Schema::create(self::TABLE_NAME, function (Blueprint $table): void {
      $table->id();
      $table->bigInteger('relationable_id')->unsigned();
      $table->string('relationable_type');
      $table->bigInteger('target_id')->unsigned();
      $table->string('target_type');
      $table->string('relation_type', 45);
      $table->timestamps();
      $table->index('relation_type');
      $table->unique(['relationable_id', 'relationable_type', 'target_type', 'relation_type'], self::TABLE_NAME . '_unique');
  });

I already used ->unique() method on classic Select fields like that :

Forms\Components\Select::make('user_id')
->relationship('user', 'v_fullname')
->unique(modifyRuleUsing: function (Unique $rule) {
    return $rule
        ->where('model_type', Company::class)
        ->where('model_id', $this->getOwnerRecord());
    })

Forms\Components\Select::make('user_id')
->relationship('user', 'v_fullname')
->unique(modifyRuleUsing: function (Unique $rule) {
    return $rule
        ->where('model_type', Company::class)
        ->where('model_id', $this->getOwnerRecord());
    })

But is there any possibility define a unique() rule on MorphToSelect fields ?

Forms\Components\MorphToSelect::make('relationable')
  ->label('Relationable')
  ->types([
      Forms\Components\MorphToSelect\Type::make(Company::class)
          ->titleAttribute('name'),
      Forms\Components\MorphToSelect\Type::make(Institution::class)
          ->titleAttribute('name'),
  ]),

Forms\Components\MorphToSelect::make('relationable')
  ->label('Relationable')
  ->types([
      Forms\Components\MorphToSelect\Type::make(Company::class)
          ->titleAttribute('name'),
      Forms\Components\MorphToSelect\Type::make(Institution::class)
          ->titleAttribute('name'),
  ]),

Thanks in advance !
