Removing forbidden cantrips from spellbook

[Dresdon]

The wizard's spellbook gets auto generated complete with cantrips the wizard isn't able to cast due to the choices taken as forbidden schools.

Is there some way to remove those cantrips so as not to clutter the character with spells they can't actually cast.

E.g. If you specialise as a Conjurer and have Enchantment and Necromancy as your forbidden schools, then Daze, Disrupt Undead, and Touch of Fatigue, will never be usable by that character and are pointless to be in the spellbook.
