Start QlikView Desktop, open your document, select any sheet you like, right-click on the sheet background and from the menu select Properties...
Go to the Security tab and disable the option "Access Sheet Object Properties". Before applying the change, also enable this option near the bottom of the dialog: "Apply to all sheets". Close the dialog by selecting OK and save your document.
Done. The Properties item will have disappeared from every object menu (but not from the sheet menu, that's another setting...)
Works without Section Access.
