With X11 it's quite simple to change all possible trackpad options through a single text file with libinput e.g.

    cat > /etc/X11/xorg.conf.d/40-libinput.conf << EOF

    Section "InputClass"
        Identifier "Touchpad Settings"
        MatchDriver "libinput"
        MatchIsTouchpad "on"
        Option "NaturalScrolling" "true"
        Option "Tapping" "true"
        Option "TappingDrag" "true"
        Option "TappingDragLock" "true"
    EndSection

    EOF

For a full listing of options:

    man libinput

The same driver is used for wayland but I don't know how you configure it there, it will no doubt be possible to do something similar with a single text file config.

I think the problem is that most UI tools like gnome settings do not expose the full range of possibilities because it's too much effort.

[EDIT]

Ouch, so i'm wrong, there is no equivalend in wayland. I know wayland has no concept of a display server but this really sucks for configurability [0]:

> For Wayland, there is no libinput configuration file. The configurable options depend on the progress of your desktop environment's support for them; see #Graphical tools.

This means there is no built in way to configure libinput without your DE/WM supporting it or other tools like libinput-config as the sibling comment points out.
