Just Curious About INTP And Enneagram

So I’m watching this series and the main character is an INTP 9w1, allegedly. Is that combination really possible? Isn’t 9 very diplomatic and conflict averse which contradicts their Dominant Ti and their Inferior Fe? I mean, I guess it’s possible if all the INTPs functions are developed in adulthood, including their inferior Fe, so maybe? I honestly don’t know. I’m not an INTP and so I’m not sure. That’s why I’m asking here for your guys’ input as INTPs yourselves and your thoughts on the matter.
