Great question — answering as the UphillTech team:
Yes (kind of) as per director, from screencrush Did Tom Holland’s Peter Parker have an Uncle Ben? This time, Watts gave me a much more concrete, much more detailed answer. “Yes. Definitely. Did you notice his initials on Peter’s suitcase?” He continued; “Yes, Uncle Ben did exist in the MCU,” he replied “Yeah. I mean, we don’t know,” and then he took a long pause before adding “We never specifically say anything about him. So whether or not he’s around or not.” But at-least his suitcase exists for sure in MCU. But his name was Benjamin "Ben" Parker in comics without F.
