In your project properties set the Enable C++ Exceptions to No:
<a href="https://i.stack.imgur.com/kDiS2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kDiS2.png" alt="Disable C++ Exceptions"></a>

and enable the unwind semantics by specifying the <code>/EHsc</code> flag:
<a href="https://i.stack.imgur.com/o4BLu.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/o4BLu.png" alt="Unwind semantics"></a>

To set this option on command line you would leave out the <code>/EHa</code>, <code>/EHsc</code> and <code>/EHs</code> flags from the <code>[option]</code> section as described in the <a href="https://msdn.microsoft.com/en-us/library/610ecb4h.aspx" rel="nofollow noreferrer">Compiler Command-Line Syntax</a> manual.

This is my experience. And practice.
To disable C++ exceptions using cl.exe, one should do all of the following:
<ul>
<li>/EHsc or any other <a href="https://learn.microsoft.com/en-us/cpp/build/reference/eh-exception-handling-model?view=msvc-160" rel="nofollow noreferrer">/EH combination</a>, should not exist as a switch,</li>
<li>/D_HAS_EXCEPTIONS=0 must be used</li>
<li><a href="https://learn.microsoft.com/en-us/cpp/build/reference/gr-enable-run-time-type-information?view=msvc-160" rel="nofollow noreferrer">/GR-</a> disables the RTTI</li>
</ul>
That combination makes <code>try/throw/catch</code> into non-existent keywords. That is: you are in the non-standard C++ territory.
The <code>cl.exe</code> compiler always generates code that supports asynchronous structured exception handling (<a href="https://learn.microsoft.com/en-us/cpp/cpp/structured-exception-handling-c-cpp?view=msvc-160" rel="nofollow noreferrer">SEH</a>)
That means C or C++, SEH is &quot;always there&quot;. I personally do use it. MS STL compiles and it is quite fast with the above switches combination. In (almost all of my) <code>main()</code> I catch the potential SE raised and then I <a href="https://learn.microsoft.com/en-us/windows/win32/dxtecharts/crash-dump-analysis" rel="nofollow noreferrer">create a minidump</a> which Visual Studio can open and lead you to the exact position in code where the exception was raised.
We need to talk about the <a href="https://learn.microsoft.com/en-us/cpp/build/reference/kernel-create-kernel-mode-binary?view=msvc-160" rel="nofollow noreferrer"><code>/kernel</code></a> switch. It switches C++ exceptions off, in one go, and instructs the linker to produce &quot;kernel mode&quot; win executables, drivers, and such. <code>/GR-</code> still has to be used manually. I used it for standard desktop/console apps with no problems. Always using SEH of course.
NOTE: <code>_CPPUNWIND</code> you can not set. But you do use it in your code to check if C++ exceptions are on or off.
HTH
PS: I always use static runtime lib's: switches <code>/MT</code> and <code>/MTd</code>. I think these days one does not need to do anything else in case dll runtimes are used, switches: <code>/MD</code> and <code>/MDd</code>. I am not 100% sure, please check e.g. <a href="https://stackoverflow.com/a/3870281/10870835">here</a>.

What compiler flags do I use to completely get rid of the exception handling?
I don't use them at all but the compiler still generates .pdata and .xdata sections which there for exception handling only.
