That is not supported by an option.  You need to change the code.

I would try to do update the keyflags in build_sig_subpkt_from_sig ()
while runnning the --edit-edit command "primary".  There are probably a
lot of side effects and thus this can only be used as a on-time hack.  I
only had a quick look at the code, thus you may encounter other
problems.
