How can I hide the OVRVirtualKeyboard Toolbar/AutoSuggest while entering a password

I've been working with the OVRVirtualKeyboard to let users create and sign into accounts.  As you can see from the screenshot, the default mode has some features at the top of the keyboard which may or may not be helpful usually, but I'd like to disable them while the user types in their password.

If you go into wifi settings on the quest 2, there is a special keyboard mode that is activated while you type in your network password.  Unfortunately it also prevents me from taking a screenshot to add to this post.

Does anyone know how to set the keyboard mode or input type?  Or otherwise disable that toolbar manually?
