@ZZTop87, Thanks for posting in Q&A. To deploy script via Intune, we need firstly ensure it can run successfully uninstall the app silently via the script on one device manually. Then we can consider deploying *it via Intune.
From your description, it seems we don't find the uninstall command. if this is a msi, based on my experience, it will have silently uninstall command. For exe file, you need to contact the app provider to double confirm if they have such command.
Hope the above information can help.
