Block usage of phone (Android 6.0.1)

[AC Question]

Hi,
I am using Android 6.0.1 and as security measure I use the "draw pattern" function, to wake up my phone as it is in "idle" mode. This is to prevent access to my phone without drawing the correct pattern.
This works well. However I noticed that it does not block access to the "quick menu", which you get when you scroll at the top of the screen to below. This menu gives you access to wifi turning on/off, location , etc.. etc.
Also, one can still shut down my phone/restart it, without having to draw the pattern.

My question:
Is it possible, and, if so, how? to configure Android to disable access to anything (the shortcut menu, on/off button, etc), without having to draw the pattern?

Anyone has an idea?

There are some custom ROMs that have a secure shutdown feature. This isn't on a stock ROM usually.

Yeah... custom ROMs.... there are a few that freeze out the quick settings toggles and don't allow you to power down the phone. I am not sure if there are any OEM phones that have the same features though.
