Hello,
Welcome to Microsoft Q&A!
Is there a way to override the three and four finger gestures in a specific app?
No, currently there is no way to achieve this.
Is it possible to programmatically read this setting in an app to notify the user that there is a problem?
I have to say no, UWP doesn't have APIs that could check the information in the Windows Settings. My suggestion is that you could directly launch the Windows Setting app when the user launches your app. Tell the users that they need to turn off the “Three- and four-finger touch gestures” in Windows settings and navigate to the setting page directly.
You could launch the setting app like this:
// The URI to launch
var uriBing = new Uri(@"ms-settings:devices-touchpad");
// Launch the URI
var success = await Windows.System.Launcher.LaunchUriAsync(uriBing);
If that URI does not navigate to the touchpad page, you could go through this document : Launch the Windows Settings app and try other URI like Mouse & touchpad
.
Thank you.
