You can also set the ships to not target planets. Probably want to tell them to not target any seekers too. They may still do so though if something else results in them being in range.

But that can let you blockade with warships that can still engage ships normally.

BTW this can be really useful in Proportions mod. Often it may be very hard to defeat an alien homeworld, but blockading it and getting it to riot can be much easier.
