part 10 bond delete 0 11
deletes a bond of type 0 to particle 11 from particle 10. That is, you need to
know what bonds you need to delete, and with which particle you defined them,
then you can delete them by using the same command as setting them, just with
the additional keyword delete.
part 10 bond delete
will delete all bonds registered with particle 10.

Yes. You can also change the type of bond, but not from harmonic to e.g.
angular, since then you don't have the right number of bonding partners.
