Interviewing with multiple teams at same company and location, do I disclose this when interviewing, or not mention it at all? (CBRE/JLL/Cushman type)

Title. I just wrapped a final round interview with a team at one of the firms mentioned above. However, I was recently contacted by a manager from another team asking if I would be interested in interviewing with them for one of their openings. My first round with them is taking place soon. I am wondering if I should mention that I have had interviews with another team at their location, or just not disclose it at all? The teams do not compete with one another. One is underwriting, the other is production. To be honest, I feel equally as interested in both roles at the moment, and don't want to create any friction or make either hiring processes any more complex. With the state of the job market, and me being unemployed, I want to make sure I handle this properly. 

Edit - To add to this, my final round went OK. I do not think it went amazing and was told that I would be hearing from them within the next few weeks since they are still interviewing candidates. If that team was not into me, then I would also like to avoid the other team getting an impression of me from them without meeting me first (the first round is conducted on zoom or phone, I believe).
