Answered how to remove minishop menu from website

First of all this is only visible if you are authenticated as a manager, so still not sure if you want to fully disable, however below are the steps to do so.

From what I can tell you should be able to update the Plugin, so in the manager go to Elements tab and then expand the Plugin folder and then expand the miniShop folder to select the miniShop plugin. Once the plugin editor is loaded click on the "System Events" tab at the top and then scroll to the bottom, then you should see and entry called "OnWebPagePrerender" that is currently checked. Uncheck that event and "Save" changes, now when you visit the page you should no longer see the menu.

Then of course to re-enable simple follow the same process and check the "OnWebPagePrerender" option to enable.
