How to create autoincrement field in Laravel without marking primary key?

Question

Laravel

Good day.
Faced such a situation: I wanted to make 2 fields with autoincrement in the migration so that they change automatically. But it turned out that the autoincrement status implies a primary key. In Google I found a way to fix it through a SQL query.
Maybe there is some other way provided by the developers?

If you are only creating a field (e.g. unsigned integer)

1. use second parameter with value true
   

$table->unsignedInteger('field', true);
If the field has already been created, then some types of fields can be changed (see the docs for specific ones):

1. describe the field the way you would like it to be
   
2. call the change() method at the end
   

$table->unsignedInteger('id', true)->change();
