Post-Offer GPA Question for a BB FO Position vs. MM SA Position. Will SA Offer get Flagged/Rescinded?

I currently have an offer for a BB FO SA position (not IBD) however my GPA has been below their minimum of 3.2. I never lied about my GPA, since I did not put it on my resume and have told people what it actually is when asked. I must have networked well enough and shown enough in the interviews to receive the offer. Will this be a problem during background checks, potentially rescinded offer? Also alternatively I have an offer at a MM shop (same division) but they have no such GPA requirement and pretty sure the background check would pass smoothly.

Will this be an issue, should I opt for the MM offer instead or take the BB? Of course I prefer the BB offer but also rather have a job lol
