I'm trying to install the "dotnet-reportgenerator-globaltool" tool via .Net Core custom task.
Custom Command: tool
Arguments: install --global dotnet-reportgenerator-globaltool --version 4.0,15
Problem: When executing from a directory that contains a nuget.config pointing to a private azure artifacts, I get an error like the following. I don't want to use my feed or need to, but because the nuget.config exists I have no choice. Is there a way I can pass credentials to this command? There is no directory that doesn't inherit the nuget.config 
[command]"C:\Program Files\dotnet\dotnet.exe" tool install --global dotnet-reportgenerator-globaltool --version 4.0.15
