Edit 2: Success! I contacted Quanta and they were able to provide me with the latest firmware!
The S210-X22RQ server is EOL and “Out of Support” as well as “Out of Warranty”. Therefore, use of provided BIOS/BMC firmware update is provided with no implied support. User accepts all risks with use of this firmware update.
