If I am omniscient, that doesn’t make me omnibenevolent. I could surely see every consequence of my actions, know exactly what would be the moral choice, and still decide to act in an evil or selfish way. Knowing the truth makes it easier to be moral, should I choose to do so, but does not make me more moral.
If I am completely absent of ability to foresee consequences of my actions, then my “morality” from a consequentialist viewpoint can be no better than random chance. Faced with complete ignorance I cannot choose to be moral or immoral, I can only do things and see what happens. Therefore it is necessary to have some level of belief in true things to be a moral agent.
Interpolating from these endpoints, it seems that believing true things is not correlated to morality so much as moral agency.
As an aside, you can imagine a situation where you are omniscient and omnibenevolent, but live in a world without moral realism. If “truth” only includes information about what will happen, and not what moral theory is “correct”, then you’re still unable to make a moral choice.
