If you're actually down to jump ship you can probably be upfront about it.
It's a negative point but the good managers I've had were usually realists so unless you have multiple questionable things or get overly defensive/weird when answering they'd just take it as "shit happens" with a small minus.
Edit: To me it feels like all of the talk outside of technical knowledge is essentially based on vibes. My CV is pretty bad since it took me way too long to graduate but after I stopped explaining it too much and just went with "shit happens, my bad" it stopped being much of an issue.
If you wanna lie you can also say that you took the job as filler until you find a position in/with CERTAIN CRITERIA and you made your employer aware of this. I don't know how common that is but my current situation is kinda this. I worked for my current fulltime employer as a student and when offered a fulltime contract past graduation I asked for a shorter notice period due to wanting to move to Switzerland and they agreed.
Of course be careful not to do it too often since you don't want multiple couple month gigs in your CV.
I dropped out of university, so in my early years it took a lot of tuning my resume to give the impression that I had a degree without actually saying it. Thankfully I had taken summer courses at a different, nearby university for two years before college. Eventually I would just put the years, the universities, and the major I was pursuing. Now I just leave it off the resume.
I had one manager who found out after the fact and told me he wouldn't have hired me if he realized, but he was glad he did.
I had an interview where they asked for a college transcript and then grilled me on why I failed Martian Geology and why I only got a C in Vector Calculus. I was given an offer, but declined it because of that experience. I dodged a bullet too; I've seen reports that the company sues former employees just to cost them money.
