Problem: When playing games on PC, pressing the Xbox controller's Guide button (the Xbox logo button) simultaneously opens both the Xbox Game Bar and the Steam Overlay.

Goal: I want the Guide button to only open the Xbox Game Bar, while keeping the Steam Overlay enabled so I can continue to use features like the F12 screenshot function.

What I've tried:

I could not find any setting within Steam to unbind the Guide button from opening the overlay.
I cannot disable the Steam Overlay entirely, as I need it for its screenshot functionality.
