How to replace Blazor default "soft 404" with an actual 404 status code response

The default Blazor approach to 404 is to create a soft 404 in App.razor, but I would like to adhere to search engine best practices to actually return the 404 status code while displaying a 404 page on Azure.

I tried to remove the element in App.razor to see if I could force a 404, however, that did not compile.

Any suggestions?
