You can add/remove Office features by way of an configuration XML and running the setup.exe. This works on removing Lync/Skype For Business from Office 2013 that has the feature already installed.
Create the XML as below saved as RemoveSkypeForBusiness.xml into C:\TEMP then run
"C:\Program Files (x86)\Common Files\microsoft shared\OFFICE15\Office Setup Controller\setup.exe" /config c:\temp\RemoveSkypeForBusiness.xml
<?xml version="1.0"?>
<Configuration Product="ProPlus">
<Display AcceptEula="yes" SuppressModal="no" CompletionNotice="yes" Level="basic"/>
<OptionState Children="force" State="Absent" Id="LyncCoreFiles"/>
</Configuration>
It should be easy enough to do this in a fixlet action. You can change the XML to make it silent if you prefer
<?xml version="1.0"?>
<Configuration Product="ProPlus">
<Display AcceptEula="yes" SuppressModal="yes" CompletionNotice="no" Level="none"/>
<OptionState Children="force" State="Absent" Id="LyncCoreFiles"/>
</Configuration>
