Asrock and some other mobo makers advise not updating the BIOS unless you have an issue that the newer BIOS specifically addresses. The BIOS updates tend to have cryptic definitions but one can usually determine if their system has a bug listed as fixed in the newer BIOS.
For those with new mobo architectures like the AM5, expect several BIOS updates until the mobo makers sort out all of the issues that occur with any new platform. It's worth noting that many of these early BIOS are "Beta" BIOS so you use them at your own risk until they have been fully validated.
