Workaround: use a NuGet.Config file with your custom feed.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <!-- DefaultPushSource key is similar to the 'DefaultPushSource' key of NuGet.config schema-->
    <!-- This can be used by administrators to prevent accidental publishing of packages to nuget.org -->
    <config>
        <add key="YourFeedName" value="---feedurl---" />
    </config>

    <!-- Default Package Sources -->
    <!-- They cannot be deleted or modified but can be disabled/enabled by user -->
    <!-- The following section is similar to 'packageSources' section of NuGet.config schema -->
    <packageSources>
        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
    </packageSources>
</configuration>

Patch it during your CI build with a powershell script.

param($file, $feedName, $uname, $pass)

$xml =[xml](Get-Content $file)

# intention is to have

# <configuration>
#    <packageSourceCredentials>
#        <feedName>
#            <add key="Username" value="[uname] />
#            <add key="ClearTextPassword" value="[pass]" />
#        </feedName>
#    </packageSourceCredentials>
# </configuration>


# create the username node and set the attributes
$userNameNode = $xml.CreateElement("add")
$userNameNode.SetAttribute("key", "Username")
$userNameNode.SetAttribute("value", $uname)

# create the password node and set the attributes
$passwordNode = $xml.CreateElement("add")
$passwordNode.SetAttribute("key", "ClearTextPassword")
$passwordNode.SetAttribute("value", $pass)

# create the feedName node and attach the username and password nodes
$feedNameNode = $xml.CreateElement($feedName)
[void] $feedNameNode.AppendChild($userNameNode)
[void] $feedNameNode.AppendChild($passwordNode)

# create the packageSourceCredentials node and append the feedName node
$credentialsNode = $xml.CreateElement("packageSourceCredentials")
[void] $credentialsNode.AppendChild($feedNameNode);

# add the packageSourceCredentials node to the document's configuration node
$xml.configuration.AppendChild($credentialsNode);

# save the file to the same location
$xml.Save($file)

Then run dotnet restore --config NuGet.Config

I went ahead and moved this to nuget/home#4126. Closing out the CLI copy.
