2016~2023 CX-9 Switch Sound After Cold-Start

:
2019 Mazda CX-9 Signature
I recently noticed after a cold start and completing the accelerated engine warmup, in 10-30sec I will get a short noise that sounds like something is switched which I believe I didn't hear before. I uploaded a video to demonstrate (the sound is at 00:12 of the video).

Can someone confirm if this is normal or what might the issue be?
 
A/C compressor? It sounds fine.
thanks for your response

I thought about it in the beginning but the thing is that the AC was not on when the noise happened, does the A/C compressor also make the switch sound when its off?
