Hi
You can disable tools by component name or itemID.
You must do this on "appsite template parameters > Features > Customize tools for page"
For example, let's imagine that you want to disable on contact page or joomla articles, you would only need to add "com_name=disabled". Each component peer line.
Here's a screenshot:

I don't know what component you are using on that specific page but if you look at url, you can easily find name of it.
Cheers
