How do I disable the auto-lock functionality on the U300?

I just installed the new U300 today and added it to Apple Home via the Matter QR code. I didn't see an option to disable the automatic locking function within Apple Home, so I downloaded the Aqara app and added the lock there. However I'm not seeing an option to disable auto-lock there either. It's installed on my garage door so it's a bit annoying that I would need to unlock the door after taking the trash out.

I thought Passage Mode was what I wanted, but it turns off whenever you lock the door again, so that's not really a viable solution.

Please tell me there's a way to completely disable the automatic locking functionality!
