Looks like the help/error message is getting confused with the "dotnet restore" version of the argument.
Repro Steps
> nuget.exe restore
NU1004: The packages lock file is inconsistent with the project dependencies so restore can't be run in locked mode. Disable the RestoreLockedMode MSBuild property or pass an explicit --force-evaluate option to run restore to update the lock file.
Ok sure, let's try.
> nuget.exe restore --force-evaluate
Unknown option: '--force-evaluate'
