Hide the Help tab for select site collections in SharePoint
If you have deployed VisualSP to your SharePoint environment via the Installation Wizard, you can choose which site collections to deploy the VisualSP solution to. Here are detailed instructions.
If you have deployed the VisualSP browser extension to your users and wish to hide the help tab in one or more site collection, your best option is to use CSS to hide the help tab. You can edit the master page, or insert a content editor web part with the proper CSS, and "hide" the #visualsp-handle selector. You will need to find a 3rd party solution from Github to insert the CSS into modern pages.
