Sounds like the OP is on a prebuilt. Installing a bios may invalidate his warranty. As you say most boards are hard to brick these days, but not impossible.
There is a lot to be gained from capitalizing on some of the later revisions, but not all revisions are good. Not all hardware will work out of the box with a newly installed revision. Definitely read up on what you are doing before taking the plunge. More importantly make a back up of your original profile and revision along with finding out what you have to do to get back to square one.
This old adage of don’t update a bios unless you have a problem does not sit well with a lot of AMD users. The Ryzen system, for all it is maturing, is still an ongoing project. The innovation level at AMD surpasses anything any CPU supplier has ever done before. There can be a lot of difference between early Agesa revision and the newer one. There is also the fact that the latest chipset driver may not be running at full potential on an older Agesa revision.
