buzzing noise on cold start

2017 1500 Big Horn owner here. Has anyone had an issue with a buzzing noise coming from underneath on cold start/initial drive? It usually lasts no more than 5 to 10 seconds but it is kind of annoying.

More info may help , under the dash ? Hood ? Front rear ? Side ?
If you could upload the sound so we could have a listen , we might be able to pinpoint.

I think it's coming from underneath towards the rear. Maybe fuel tank/pump related? I'll try and record and upload.
