Summary of the new feature / enhancement

DSC Install required prerequisites – as parameter or force in installation process

Hello I like to suggest option to install prerequisites for DSC engine similar to Winget as it export configuration to DSC file, as new PSResourceGet PR contain PowerShell/PSResourceGet#1950 integration with PowerShell gallery and MAR it will be nice to have not manually install this dsc additionl things as a separated process or manual copy those files across environment.

Proposed technical implementation details (optional)

Technical propusal for this

dsc setup --force  #silent with overrride option

or 

dsc setup --install # prompt interactive with select [Y/N]

Base on for example perquisites json file or schema like this it will install required components
