Thank you. I鈥檝e been using the foxy documentation even though I鈥檓 on Jazzy. The new documentation style is just not readable for C++ projects.
PS: There is a way to disable the Sphinx/Breathe documentation generation: Allow show_doxygen_html and disable_breathe options by rkent 路 Pull Request #173 路 ros-infrastructure/rosdoc2 路 GitHub but I haven鈥檛 tested it myself.
