either use raw sql query:
$rows = DB::select("SELECT * FROM users");
dump($rows);
or play around with cursors (https://laravel.com/docs/10.x/eloquent#cursors), but it uses LazyCollection, so it "processes" it somehow anyway, but afaik does not create a model instance (not sure, you need to tinker a bit):
$rows = DB::table('users')->cursor();
foreach ($rows as $row) {
//row is an array
dump($row);
}
