How to remove page titles in Scripted theme

I’m using the Scripted theme and I’ve created a child theme. I would like to remove the page titles from my “About” and “services” page.

I have also added a category to my navigation menu, and the category name shows up as a page title when I navigate to it.

Is it possible to remove this?

I tried using the Hide Title plugin and it works for the About and Service page, but I can’t apply it to the Category page.

The issue with using the plugin is that when first navigating to the “About” or “service” page, the page title briefly flashes on the screen before disappearing, so that’s no good. I’d prefer to get rid of it entirely.

Thanks for your patience, I’m completely new to this!
