Hi Sascha,
Thank you for using Syncfusion Products.
The ToolBarItems can be disabled by using
{
m_ReviewToolBar.Items[2].Disabled = true;
}
Regarding the disable of toolbar-items placed inside the template, it can't be disabled using above code because the controls inside template may have different properties and methods. So please refer the below online sample which illustrates getting the properties of controls placed inside the template and disabling of dropdown control and the sample files can be downloaded from 'Download Source'.

Please let me know if you have any concerns.
Thanks,
