Latitude 7424 -- Erratic Touchpad

Hey all, just received this laptop yesterday, and it's working great! One problem that I can not seem to fix is this Touchpad manages to be both too sensitive and too slow simultaneously. Scrolling using the two finger gesture is intermittently resistent to my touch. It doesn't happen a lot, but when it does, oooh boy does it resist moving my mouse icon to a specific cluster of pixels. In addition, the mouse icon takes a bit of work to move from one end of the screen to the other (not a lot), and in the process, the mouse icon will randomly jump to the side in any direction when I'm trying to click something small on my screen. And scrolling with the gesture, going back to that, it seems resistent to start scrolling, and a little too fast at it when it finally does.

Things I've Done To Troubleshoot: (Regarding the erratic jumping around, not the scrolling)
1) I've read the manual for starters, and seen the two steps it offers for fixing/diagnosing an erratic Touch-Pad.

2) I've tried lowering the sensitivity setting, and raising it to High, and I don't like the icon being at slow sensitivity, but no setting seems to stop the touchpad from randomly jumping around intermittently.

3) I've updated my Drivers up to the latest versions, which I assume includes the Touch-Pad driver, considering the Dell utility doesn't seem to detect one for it anymore, if it did in the first place.

4) The Laptop manual states to attempt pressing semi-firmly on the case where encompassing the Touch-Pad. If pressing on the case near it on any side causes the mouse cursor to move on its own, then it's a Hardware fault of some kind, and needs to be replaced.
4--B) The above was tested and did not appear to be the case. So, my drivers are up to date, and hte Touchpad does not need to be replaced afaik.

5) Finally, the crux of this post. A video regarding this issue on the latitude 7440 states that Gesture settings can cause some degree of instability in how the Touchpad operates. I can not find any settings, in Windows 10 Pro x64, pertaining to enabling/disabling special Gestures for hte Touchpad.

Could someone tell me where I can disable Gestures for this particular model, and if you have any other ideas for making my Touch-Pad function stability when trying to select things and scrolling around, I'd be open to suggestions therein as well. :)
