Laravel upload a big CSV efficiently

I am trying to upload a CSV file to my database in laravel. But my CSV file is pretty big, I almost have 500 million rows that I want to import. (I am using Maatwebsite to do this)

And when I try to import it I am getting:

Maximum execution time of 300 seconds exceeded

As you can see I already changed the "max_input_time" in the php.init file. 300 seconds would be enough because datagrip takes only 3 minutes. And even if it would take longer in laravel there has to be another way than increasing the "max_input_time"

this is the code that’s converting the data in a model and evantually putting it in de database:

public function model(array $row)
    {

        return new DutchPostalcode([
            'postalcode' => $row['PostcodeID'],
            'street' => $row['Straat'],
            'place' => $row['Plaats'],
            'government' => $row['Gemeente'],
            'province' => $row['Provincie'],
            'latitude' => $row['Latitude'],
            'longtitude' => $row['Longitude'],
        ]);

    }

this is my controller:

public function writeDutchPostalCodes(){
        Excel::import(new DutchPostalcodes, 'C:UsersMoemeDocumentsProjectsahmo appsAppsfreshnessFreshness - beFreshnessBEresourcespostalcodespostcodetabel_1.csv');
    }
