If you want to make a TOC filter that does not display certain headers you can use toc:exclude. For example if I want to exclude headers that have the word Our or the word Ticket in them I can use:
{toc:exclude=.*(Our).*,.*(Ticket).*}
The comma totally separates out each element so I had to surround each word with .* to make sure they both worked. .*(Our),(Ticket).* would not work.
