Disable tablet version

Hi everyone,

The Hueman theme is responsive, it has 3 versions: desktop, tablet and mobile.
I like the desktop and mobile version very much. But unfortunately, I don’t like the tablet version.
The reason is that I use the sidebar for navigation. As in the tablet version the sidebars are not visible until they are manually expanded, I think this could cause visitors to get lost.

Would it be possible to disable the tablet version with a couple of minor changes to the css of a child theme?

Any advice is welcome!
