If you want to install the driver, you'll need to open the .cat file and import any certificates that show "untrusted" into the Local Machine / Trusted Publishers cert store. You may also need to disable driver verification and/or disable secure boot in the BIOS in order for it to accept the cert and allow the driver to load.

How to extract the certificates from the CAT file? I searched the directory & found only one CAT file there, can you explain the process in brief?

Right-click on the cat file. Open it to view. View the certificate chain and look for the ones with the red "x". Open that cert and "Install Certificate".

So, as you instructed, I opened the CAT file & install each of those RED five certificates manually twice, once for 'Current User' & another time for 'Local Machine' and then after installing all of those 5 certificates, again I tried to update the driver from device manager from the downloaded package, but with no luck. Same error, screenshots attached. Any more suggestion to follow?
