I just installed the macOS High Sierra (10.13.4) from scratch on my macbook air 11 '2011. Before the trackpad worked perfectly, after installation, it returned to the standard with physical click and drag with 3 fingers. but no setting is available in the settings, and appears as trackpad not found. apparently it does not appear anywhere with system, and I can not configure the gestures.
MacBook Air, OS X Mountain Lion

From the Desktop, hold down the Shift+Option keys and then click on the Bluetooth menu item to reveal the Debug menu
Select “Reset the Bluetooth module” from the Debug menu list
reboot the Mac as usual

If that does not resolve your issue you can
trash Bluetooth Preferences and shutdown the Mac.
Delete the Bluetooth plist file from the Finder>Go>Go To Folder copy & paste:
/Library/Preferences/
Delete the file named “com.apple.Bluetooth.plist” and (you can also delete the com.apple.Bluetooth.plist.lockfile too— you will need to enter your admin psswd.
(please note psswd are not echoed on screen.)
After deleting the com.apple.Bluetooth.plist file
Shut Down the Mac.
Before rebooting the machine, reset the System Management Controller—this dumps many core hardware settings and power functions.

1 Choose Apple menu > Shut Down.
2 After your Mac shuts down, press Shift-Control-Option on the left side of the built-in keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds.
3 If you have a MacBook Pro with Touch ID, the Touch ID button is also the power button.
4 Release all keys.
5 Press the power button again to turn on your Mac.
Once you are fully booted, from >System Preference>Bluetooth resync your hardware

Sorry, the screen shots above showed Bluetooth.
See >System Preferences>Trackpad
Use Multi-Touch gestures on your Mac

For your internal trackpad if no luck,
Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
This did not work. I would like to remember that I am trying to access the gesture adjustments of the built-in trackpad of the macbook and not an external bluetooth. I also noticed that there is no trackpad / multitouch .plist in the precerences folder
I do not have any bluetooth devices, but trackpad settings only look for one, and bypass the integrated macbook trackpad. Before updating to the High Sierra in Settings> Trackpad I could activate gestures, now only shows the option to search bluetooth trackpad (according to the image). The trackpad integrated in the macbook operates normally, but I can not configure the gestures because the macos apparently does not recognize it in the settings.
I tried again to follow the steps up, but they did not work out.
I would try re-install the macOS on top of your existing MacOS.
You can do this from Recovery.
