System Firmware Version is: 481.0.0.0.0

Most recent one.

OS Loader Version 540.120.3-37

This is tied to the macOS version.

If not how to update?

MacPro6,1 (with the factory installed or a compatible SSD) and later models do firmware updates automatically via Software Updates, no need for user intervention.
