Unfortunately you cannot do that. The only way to change gallery route without modifying any line of code is using route filter. You cannot do it per style basic.The main issue is that I want to change the gallery tab link per different styles. Our main layout has splash pages that offer a content warning, and I would like to create a secondary layout that removes these warning pages for more experienced users who do not need or want them.
I had at some point previously managed to manually change the gallery tab's address but have since been unable to locate where I made the change.
