I'm sorry, your post doesn't make much sense. Can you again explain what you want? Your title says "nvidia drivers", but your post say "mount from USB device". You mounted what? For what?

Apologise, what i mean is i save Nvidia diag driver Deb file on a usb thumb drive

Next i did a sudo fdisk -l to look for the usb thumb drive and i'm able to see /dev/sb1 which is the usb thumb drive containing the nvidia deb file

But i'm clueless how do i install the deb files from /dev/sb1 as in what the command i could execute to run the installation

You will need to know the mountpoint of USB drive and can then try
sudo dpkg -i /media/USB/*.deb (change USB to whatever your system mountpoint is) but never having used an nvidia driver I have no idea whether or not there are dependencies needed to allow this installation.

Unfortunately, dpkg does not handle dependencies, but it should tell you what extra packages are needed in error messages, which you will then need to download separately, add to the USB and run the command again.
