Loud popping noise while parked

Hey guys. When I had my car parked in the garage, I kept hearing this loud popping noise. It sounds like. Backfire almost. I believe it is coming from under the lr seat or the rear trunk area. It does it every 30-60 min or so. It’s definitely jarring to hear if

temperature changes in battery? is this after a drive?

does it eventually settle down?

Cars been parked stable temp in the low 60s in garage. I was doing my tints and I just keep hearing the car making these noises

is the car being charged or left idle?

Idle

My TM3 have this noise too. I found that this noise is only when Sentry activates, or I open a door or the car is charging. And even cancelling any of these, the noise keeps for 10 minutes at least.
