Reference article : How to hide an entry in the Add/Remove Programs applet?

In Wix source files, set property ARPSYSTEMCOMPONENT = 1 would do this, for example:

<Product> 

      <PropertyId="ARPSYSTEMCOMPONENT">1</Property>

</Product>

Reference: https://www.mail-archive.com/wix-users@lists.sourceforge.net/msg15696.html

When you set ARPSYSTEMCOMPONENT you‘re telling Windows Installer, ‘this is a
system component, don‘t show it in Add/Remove Programs‘.

WIX: Hide installed program from the Add/Remove Programs window.
