The ability to disable the X/Y-axis lock for touchpad scrolling is not directly configurable through standard Windows settings. Windows imposes certain limitations on touchpad gestures, and while there are some registry settings that can be adjusted for touchpad behavior, they do not specifically address the X/Y-axis lock issue you are experiencing.
For precision touchpads, the settings available in the registry primarily focus on enabling or disabling gestures and adjusting their behavior, but there is no specific setting documented that allows for the removal of the X/Y-axis lock during scrolling.
If you are looking for a workaround, you might consider checking for any driver updates from ASUS for your touchpad, as manufacturers sometimes provide enhancements or fixes that could improve touchpad functionality. Additionally, third-party software solutions exist that may allow for more customizable touchpad settings, but these can vary in effectiveness and compatibility.
Unfortunately, without a direct setting in Windows or the touchpad driver, achieving the desired behavior may require more complex solutions than simply adjusting settings.
