I'm guessing that your planning to migrate to another Antivirus vendor or upgrade to another version of SEP. (SEP can upgrade over older versions btw).  When you follow your appouch you leave the computers unprotected. A big security risk

I would recommendt to combine the uninstallation of the old antivirus software with installation of the new one to minimize the time your computers are left without protection. The same script to uninstall old AV and install new.

Also: if you wish to uninstall through CMD  its easier to use the command below. That way you don't need to update with new MSI string everytime SEP comes out in a new version.

wmic product where "name like 'Symantec Endpoint Protection%'" call uninstall /nointeractive
