Emmmm from memory there is a reg key you can use to adjust this. I think they call it curtains in windows 10/11. I’ll see if I can find anything.

Edit:

This might not be it, but I’m currently on phone away from the desktop and I struggle to do any meaningful hunting the web on a phone. But have a look at this, might help your needs.
