Answer 1

If you don't wanna update all your code, you can also achieve same by one line config using Apache or Nginx configuration(or any other HTTP server/proxy that you are using)

1 Setting SameSite cookies using Apache configuration

You can add the following line to your Apache configuration

Header always edit Set-Cookie (.*) "$1; SameSite=Lax"

and this will update all your cookies with SameSite=Lax flag

2 Setting SameSite cookies using Nginx configuration

location / {
    # your usual config ...
    # hack, set all cookies to secure, httponly and samesite (strict or lax)
    proxy_cookie_path / "/; secure; HttpOnly; SameSite=strict";
}

Same here, this also will update all your cookies with SameSite=Lax flag
