1st option, revoke ‘edit_theme_options’ capability the user role.
If for some reason you wish to leave ‘edit_theme_options’ capability to a role, for access to some menu item under ‘Appearance’ menu for example, then,
2nd option, you can enable “Theme Options” admin menu item using “My The7 -> Show theme options in sidebar” checkbox. After that just block “Theme Options” admin menu item using “Admin menu access” add-on. This will automatically block “Theme Options” top admin menu too.
