Parker here from the Guru team :)
May I ask the reasoning behind wanting more items in your navigation? I like to recommend sticking to around 6 navigation links so as to not clutter your header. Making use of drop down menus to get more information/products available. That being said, not everyone has the same opinion as me ;)
To stop the navigation from creating that More drop down, you would just need to comment out the code that is creating it. This can be found in the theme.js under Assets when you go to Online Store > Actions > Edit Code.
Before making any coding changes, be sure to make a backup to ensure you always have a working copy of your theme. I would love to take a look at your site! Feel free to share a link to your site for some feedback :)
I hope that helps!
