@Samuel Santos, Thanks for posting in Q&A. To uninstall the Acronis from all workstations, we need to firstly find out the uninstall commands. After researching, I find a link list one command. You can test it on one device to see if it works. If not, you need to contact Acronis support to get the uninstall command.

Note: Non-Microsoft link, just for the reference.
After we get the uninstall command, we can deploy it via PowerShell script in Intune to run it on all the workstations to remove the app.
