Steinberg have decided to not offer any “remove” function - for neither plugins nor instruments. I’m still struggling with this weird design decision myself.
Instead, you need to click on the plugin/instrument name (kontakt, fm8, whatever) inside the instrument rack. When you do, the list of your installed instruments will show up. Browse to the top of that list, and select the option “No VST instrument”. That’s how you unload both plugins and instruments nowadays.
