NVC has no authority to deny visa applications. It's the consulate that has the authority. If you withdraw your I-130 and I-864 as recommended here, the consulate will not proceed with visa processing at all. They will not bother conducting the visa interview and denying the visa. Your husband will find out eventually, if he asks NVC or the consulate.
But, if you don't withdraw your I-130 and I-864, it's very possible that your spouse will proceed with the interview and be granted the visa. As mentioned above, you will be financially responsible for your spouse after he enters the US, whether you like it or not. And divorce will not end your I-864 obligations.
