Also building on @NikolayP's answer:

NuGet currently supports the command line argument -ExcludeVersion for the install operation. From the docs:

Installs the package to a folder named with only the package name and not the version number.

For easy copy and paste (adjust the NUnit version to your requirements):

• Executable: %teamcity.tool.NuGet.CommandLine.DEFAULT%\tools\nuget.exe
• Parameters: install NUnit.Console -Version 3.7.0 -ExcludeVersion -OutputDirectory %system.teamcity.build.tempDir%\NUnit
