c# 8 nullable types - replace var keyword with explicit type properly

Hello,

Is there a way to set the behavior of the context action 'replace var with explicit type' so that when the type is not null, it does not add the nullability mark?

As below, the string is surely NOT null, so it should be possible to NOT add the ?.

I am aware that I can assign it null in the future, but it should not be the default, but rather explicit.

Kind regards,

Bartek
