MacBook Pro 2017 - Keyboard & Trackpad issues

I have started using a Apple MacBook Pro 2017 (15 inch) around two weeks back.

I have been little unproductive since then because of keyboard and trackpad issues:

I don't want to use dragging with drag-lock or using three fingers. I don't want to reconfigure all other things to use four finger gestures.

Unlearning something is painful and frustrating. I am happy to learn new things if I think those are better than old ones. I don't think that's the case here.

I will update this post if I find some other issues.
