It varies by manufacturing date. You're likely safe since the board probably has CPU-free BIOS updates available.
Third generation Ryzen refers to the Ryzen 3000 series, not the 5000 line. The 5800X isn't from the third-gen Ryzen either. If the B550 motherboard came later, it likely has an updated BIOS—though I’d be happy to help update it if possible. Sometimes AMD’s naming can feel confusing; the Zen 3 architecture is what defines the 5000 series, not a separate "third generation" branding. The Ryzen 2nd generation used Zen+ instead of Zen 2, which does change how things are organized.
