Most likely, but it's really likely your partner never knew he had it, and had it before you started the relationship.
HPV clears from the body within 2 years for 90% of those that have it, and since you didn't have an HPV test in 2019, you won't ever know with 100% certainty that this came from your new partner, but chances are really good that it did.
By itself, it is not nearly enough to indicate cheating, though. HPV is incredibly common - it's estimated that up to 90% of us will get it at least once in our lives - and a lot of the time, we don't ever get symptoms.
The most important thing is following up and doing what the doctor is recommending for treatment.
