However, one might also simply be in the position of no opinion because of the belief that one does not have enough information to form what one would later believe to be a valid sound opinion once enough information has been gathered.
I've emboldened certain words in your quote - the initial question of this topic was: can there be an absence of belief. In your answer there is still belief. belief for or against or that you don't have enough information to have an opinion. in each case there is belief.
Pardon. That is my humor. I like to play on words and I was responding to the other part of your question (the part I quoted). I will rephrase.
However, one might also be in the position of no opinion because of the opinion that one does not have enough information to form what one would later come to the conclusion that it is a valid sound opinion once enough information has been gathered.
As to whether there can be an abscence of belief, no. It becomes useless once knowledge is gained but knowledge is sought with belief first. Also, belief in nothing is belief in something because nothing has the state of being nothing and is therefore something.
The closest to being void is zero which is "between" and therefore exists. The only way to surpass zero- or going from point A (1) to point C (-1) while avoiding B (0) is a wormhole or triumphing over Space and the wormhole is something. You then have to move fast enough to make Time slow down. (When Time slows down your perception of events is rather like in the show The Six Million Dollar Man. It feels fast and slow simultaneously.) You still have to believe you will get to point C and bypass B the first go unless it happens unexpectedly.
ie I found myself to be in a totally diffetent part of a library than I had been in and my head was gently turned and my eyes focused on the spine of a book that turned out to be important and I was not looking for it either. I simply suddenly was seemingly transported. I did not expect that to happen let alone have time to believe it would. It is only human to believe first even if your theory seems sound. Once you prove a theory via experience, belief can be tossed.
