Changing system font

[jt0x]

Am I able to change my system font with Open-Shell? I recently changed my system font to italic Segue UI and, when I started my PC this morning, it was changed back. I don't remember using any other customization software but I can't find an option to change system font in Open-Shell. I'm not a frequent github user, so I apologize if I posted this in the wrong place.
