See:
https://github.com/PowerShell/PackageManagementProviderResource/blob/master/DSCResources/MSFT_NugetPackage/MSFT_NugetPackage.psm1#L414

The order of the parameters are incorrect so a message like this can be recevied:
You are installing the module 'Git-Trusted-Certificates' from an untrusted repository 'Trusted'. Your current InstallationPolicy is
'https://nexus.contoso.com/nexus/service/local/nuget/nuget-hosted/'. If you trust the repository, set the policy to "Trusted". "Untrusted" otherwise.

Line 414 should be:
Write-Warning -Message ($localizedData.InstallationPolicyWarning -f $Name, $packageFound.Source, $InstallationPolicy)
