You can use browser detection to detect the user request header which is modified by users on clicking  F12 key in order to  determine what version of document mode users are trying to change, and modified  the page's user-agent  in the header information  before send or response back to user's browser.
For example only,
Users call financial.php to your server and in your finanical.php you have code something like that as follows and the re-send the page to users with or without condition similarly in Example-1 and Example-2
and with your wishing user-agent information for users that will force user to following your rule to view the your-original-finanical.php webpage.

Hope understand your question completely. If not , please point it out.
