I think he's asking to *ungroup* the icons. I.e., this what SuperUser post is talking about: Any way to "ungroup" taskbar items in Windows?
Prior to Win11 24H2, you could combine StartAllBack and 7+TaskbarTweaker to get the desired behavior, but it no longer works in 24H2 because StartAllBack was forced to write a new taskbar from scratch, for that version, rather than relying on existing Windows code.
