How to set “Override high DPI scaling” to “Application” programmatically through code

Question

We have a control inside a activex control that suffers from graphical artifacts on Windows 10. It works fine in Windows 7. The only way we have been able to fix the artifacts is by changing the exe setting pictured below.

Is there a way to change it through code (Visual Studio 2017 c#)? In our project we dont have a manifest file in project.
