When publishing how do I target specific .NET Core Runtimes?

Target specific .NET Core Runtimes, specifically the win RID because that is the only platform I am targeting.

On my CI/CD server I publish my applications with this command:

dotnet publish -c Release -o ..\publish

It outputs a runtimes directory with the following sub-directories:

    - publish/runtimes/
       - debian.8-x64/
       - fedora.23-x64/
       - fedora.24-x64/
       - opensuse.13.2-x64/
       - opensuse.42.1-x64/
       - osx/
       - osx.10.10-x64/
       - rhel.7-x64/
       - ubuntu.14.04-x64/
       - ubuntu.16.04-x64/
       - ubuntu.16.10-x64/
       - unix/
       - win/ 

Is there a way to configure the project to only output the win runtime folder?

Scope
I only plan to publish this application on Windows 2016 Server so the OSX/Linux/Unix runtimes folders are not necessary. In several cases these runtimes folders contain known vulnerable dlls which lead to false positive OSA scans.

Why do i request this?
I have tried adding the win10-x64 and win10-x86 RIDs in the my project file's element:

<RuntimeIdentifiers>win10-x64;win10-x86</RuntimeIdentifiers>

The output of adding the RIDs to my csproj files is the same as if I did not specify the RIDs in those files.

When I run CI/CD command example

dotnet publish -c Release -r win10-x86 -o ..\publish

I believe it creates a self-contained deployment. As my publish directory goes from being 55MB to 120MB and from 237 files to 482 files. It also matches the output if I included the --self-contained flag.

Thank you for your time and help!
