We are working on an SK, I'll share its details soon.
There are 23 hardcoded upgrade codes of Symantec products.
Search and removal of these product families can be triggered by adding REMOVESYMANTEC=1 property to the command line.
In addition, there is an option to remove any other MSI-based products passed in REMOVEPRODUCTS property by ProductCode or UpgradeCode.
For example:
EPS.msi REMOVESYMANTEC=1 REMOVEPRODUCTS={8D92DEB1-A516-4B03-8731-60974682B69C};{23170F69-40C1-2701-0000-000004000000};{9BE518E6-ECC6-35A9-88E4-87755C07200F}.
