You can't without unloading the application. The point of memory
mapping an executable is to allow it to be loaded on demand rather than
wasting RAM holding executable code that is never called. The point of
locking it is to prevent the executable code changing while it is
running.

Fundamentally you are trying to do something that is inadvisable -
modify a running executable. There are some techniques and situations
where this is a viable and neccessary activity but those are pretty
rare.

I suspect you are writing an installer or installation support tool. In
that case the only thing you can do is write a program to unload the
target application, apply the update, then relaunch the target
application.

I believe that Windows supports the concept of 'copying at bootstrap
time' for those executables that can't be shutdown and restarted
without a reboot.
