We had it in the past but it was removed. Deploying a process (I will use process instead of robot) requires deploying the actual UiPath runtime… in the end you will still be installing UiPath Robot. Only that it will complicate the setup, especially if you want to deploy 2 processes as exe. You don’t want to end up with 2 UiPath Robot installations.
As a workaround deploy UiPath Robot and then create 2 exe files that invokes your xaml package.
