Removing VST from rack 7.5

I see that I can power off a VST when placed into a rack, how do I remove it permanently. Thank you.

This has been covered so many times , Click on the instrument name in the rack and select none

Thanks, it would be nice to have the same paradigm for removing other items such as effects, just drag them out. Perhaps it is why the question is asked so many times, not that obvious. Thanks for the quick response.
