Setting borderless window position

Hey, if I run the game in borderless window mode with lower resolution than my screen, it will run centered. That’s nice, but I need it in top right corner, when I want to stream it comfortably. Is there somewhere any config file, where I can edit these settings?
Thanx

EDIT: I know about the trick how to move borderless window with windows start panel, but sleeping or waiting in game actually resets game window back to center again. That’s why I’m looking for permanent solution.
