Hide the tools pane for all pdf document

In Acrobat Reader DC, I want to hide tools pane completely for all documents I open. I'm aware of this current setting where I can set to remember the current state of tools pane. But I work on a project where all the documentation is in pdf and they are hundreds in number. I can't expect to apply this setting for all the document by opening one by one. How can I set this option once to be applied for all the documents I open using Reader DC?
