Customize the Palette theme - nav bar

Hi, I just installed the latest Version 9.4.7 and I am trying the Palette theme. The navigation bar have this animation thing with dots over them when hover over it, I would like to remove that. In the Design & block template, I can only choose different templates, but it does not look like I can change this.
I have tried to look in the control panel too, but I can’t spot where I can edit this?

I already changed a few things and deleted pre-content from this template, to make it look more simple, but if I change back to the Atomik theme, then I will need to start all over?
