Is the game you playing don't have button configuration?
You can try to override it by using some 3rd party app such as AHK

AutoHotkey (AHK) is a lightweight automation tool for Windows that lets users create custom scripts to control their keyboard, mouse, and system behavior.
One of its most useful features is button configuration, where you can remap keys or assign complex actions—like launching programs, typing preset text, or performing multi-step commands—to a single button press.
This makes repetitive tasks much faster and more efficient. With a simple scripting language, AHK is accessible even for beginners, yet powerful enough for advanced users who want to fully customize their workflow and boost productivity.
