The methods vary between command line tools.  You can for example
disable the 'manpager' USE flag for sys-apps/man-db. The manual page for
emerge mentions different methods (search for "--color"). Depending on
the terminal software you use, you might be able to select monochromatic
colour profiles (iterm2 for macOS does support this).
