ConnMan does not do any additional profile based configuration, so that
has to be added by an external program.
The perhaps easiest way of solving this would be a separate tool, which
moves (copies) required ConnMan .config files to and
from /var/lib/connman. The ownership of that directory should be set
properly, as the current root.root user and owner is merely just a
placeholder for the tool developer or distro maintainer to update when
needed.
The easiest solution might be to store all .config files relevant to a
certain "profile" in a specific directory, e.g.
'/var/lib/<name-of-tool>/profiles/<name-of-profile>/*.config'. Based on
user selection the .config files based on the previous profile are to be
removed with the .config files for the new profile added
to /var/lib/connman. It is a good idea to remove only the previous
profile specific .config files from /var/lib/connman and not every file,
as some other program(s) or the user him/herself may have added
specific .config files for some other purpose than the profiles handled
by this tool.

And that would be '/etc/connman/main.conf'.
