Hello,
The video is not very clear as filmed from inside the vehicle
Your vehicle is equipped with the 6speeed F40 manual transmission
There are no known issues with 1st gear noises, there is a factory bulletin regarding 4th whining noise which obviously does not apply
I would suggest first lifting the vehicle in front, securely supported, and seeing if you can reproduce the noise with the front wheels in the air. You could then take a new video at the transmission.
Suggest to also check the transmission for leaks, check transmission oil level. If drained the total fill quantity is 1.7L, 1.8 quarts.
A new drain and filler plug should be installed, tightened to 30Nm
