Yes, you can change the title, text and the readmore via Appearance >> Customizer >>Unconditional Services Options tab.

I’m liking the theme, but I have four areas of content. Is it possible to add a fourth services (widget)?
YEs, I had to do the same thing … I edited the Boxes.php and added a 4th box. Then if you want to customize it, you have to edit the customizer.php and create a servic4 section. For both the boxes.php and the customizer, just cut and paste from other sections, and change the numbers to a 4.
A note of caution: Although the suggestion by @walker13 is correct all edits should be done via a child theme and not to the theme’s files.
