No.. Its not possible to prevent any command of browser. One thing that you can do is just to disable the features just not showing them to the user.
Just open the page in a new window using window.open (most of the banking sites does that) with all toolbar, menubar etc hidden and disable context menu.
You can take a look into this on how to disable Right - click context menu from your website.

Also, most of the browser doesnt allow to hide addressbar. So dont show any sensitive information as querystring.
I hope this will partially solve your issue.... :)
