Unlikely to happen straight away. Due to a quirk of the Fixed Term Parliaments Act 2011, a successful VoNC now would allow the Prime Minister to run out the clock by refusing to resign, waiting the maximum two weeks to attempt a superseding Vote of Confidence, then calling the latest legal election after he inevitably lost. And Parliament would then be dissolved for the election, leaving only Johnson at the controls over the critical period leading up to Brexit day. There are other routes out of the situation after a VoNC, but they involve Parliament being able to agree on a new PM, which is tricky given that the Leader of the Opposition is cordially despised by much of the Commons and there are deep political problems with any of the other potential candidates. It also would require Boris to either resign or be sacked after losing the VoNC, which is by no means a done deal given that he's ignoring all the other conventions and there's no obvious mechanisms for a forcible dismissal (one hasn't been needed since the early 19th Century, as PMs have done the decent thing on losing the confidence of the House).
