@EpicPenguin Thanks for posting in our Q&A.
From your description, did you mean that these apps are installed manually, not deployed via intune? If yes, there is no direct method to uninstall them via intune.
Or it is suggested to try to uninstall these apps via Powershell scripts. We can deploy scripts via intune.
