Override Cookie constructor in laravel 5.5 to allow rendering site inside an iFrame

Laravel 5.5 will only accept lax, strict or null as sameSite options when setting a cookie and will throw and exception if it is not one of these – before you ask I am stuck with laravel 5.5 for now.

To allow the site to render in an iFrame the cookie needs to be set to SameSite: none

Changing the code in vendor does work, but is not a solution, so I looked at extending the Cookie code and using my own constructor.

I found this ticket:

Laravel 5.5 Override vendor class

but the code I would like to change is in Symfony: vendor/symfony/http-foundation/Cookie.php and there is a CookieServiceProvider in Illuminate with is returning an instance of CookieJar which I can see creates a new instance of the symfony cookie in its make() method

Is there a way to extend the symfony code so that laravel uses my version of the constructor?
