This is what the source code said to me too.
I'm going to have to fall back to directly interacting with LDAP to make
this work, or set up PWM though we'd prefer an official and supported
password manager plugin for FreeIPA.

No, nothing would allow you to change pre-hashed passwords through IPA
What you could do is to set them a random non-hashed password as
administrator and thus it would force to change the password on next login.
That's all you could do. Of course, 'next login' can be simulated too, but
you cannot do this with a hashed password.
