Remove Server header when using UseHttpSys()

[OnamChilwan]

Is it possible to remove the Server header when using UseHttpSys()? I see the type HttpSysOptions but there doesn't seem to be an option which allows me to remove the header. Is this possible to do so within the app or is it highler level config?

Thanks.

Triage decision: We won't be doing this in the server

@shirhatti can you please share the reasoning which overweighted the arguments from this discussion: aspnet/KestrelHttpServer#852 (comment)

HttpSysServer isn't the one adding the Server header, it's done by the lower level http.sys component and there's no API available for us to control that, only some workarounds like those mentioned in the blog.

I see, makes sense. The workaround didn't work for me. Most probably this is my local issue, as I'm testing cert client auth and getting 403 so the lambda to removed the header isn't called yet.
