What is best practice to modify Vendor views?

Let say I set new CI4 instance, then put Shield (Auth) with composer which reside under Vendor folder.
CI4 will autoload Shield including all "Pre-made" views (login+forgot password+register+etc)
So how to move Views for our main project instead "Vendor's belonging?, because if we modify those Views under Vendor, then it all will be replaced whenever we do Composer Update.
