Thank you for posting your inquiry on the NVIDIA Developer Forum - Infrastructure and Networking - Section.
If you install the latest WinOF-2 driver, the f/w will be upgraded automatically during driver install. In case you adapter is an OEM adapter (HPE/Dell/SM/Lenono), this f/w upgrade will not happen and needs to be done manually as you need to download the correct f/w image through the OEM website.
Instructions on how-to burn a new f/w manually on the adapter you can find through the following link →

the attached Document on your last post, Page 3 (top) at the PCI Express interface Section 4th point down:
Auto-Negotiates to X16,x8,x4,x2,x1 lane(s)
based on this:
I need to move the ConnectX-5 card from Riser 2 to Riser 1A. correct?
