Check the info in this post in order to learn how to manually complete the new update before Google rolls out the update in your region. In case you are an advanced user, then you should be able to manually install the new official Android 8.1.0 update using the ADB Sideload method.

Before starting the installation you should check the guidelines below.

Preparation Steps:

This guide has to be used only for the Google Nexus 5X devices.

Don’t attempt to install the new update on any other Nexus models.

Enable USB Debugging and OEM Unlock from the Developer Options menu.
If you cannot find Developer Options, then you should enable this menu first: go to Settings> About Phone and tap seven times on the Build Number text. Return to Settings, and the Developer Options menu will now be listed there.

You should install the new Android 8.1.0 OPM5.171019.015 February 2018 update over older Android 8.x version only. Don’t attempt to install the new update over older Android 7.x builds, as the installation will not work.
