A plugin can be built from the command line with the following command:
<PathTo>/RunUAT.bat BuildPlugin -Plugin=<path_to_.uplugin> -Package=<path_to_empty_directory>
Not sure what that does though.
June Rhodes made a PowerShell script to help with plugin development. Can probably be read to learn more about what command line arguments are useful: https://gitlab.com/redpointgames/unreal-engine-plugin-build-scripts/-/blob/master/Build.ps1
