A compatibility feature between the page builder and the Gutenberg editor was added to WPBakery s 5.5 update which was released on the 7th of June 2018. If you have WPBakery version 5.5 or later installed you will notice two options connected to the Gutenberg editor: the Gutenberg editor and the Classic editor.
When you select the Gutenberg content element from the Add Element menu you will be able to put Gutenberg layout/blocks straight into the layout of WPBakery Page Builder or Visual Composer (Please note that you can insert an unlimited number of Gutenberg editor instances on the same page).
In the WPBakery Visual Composer Settings there is an option to disable the Gutenberg editor on your WordPress site (in your WordPress Admin Dashboard).
