Windows 10: Flash to new BIOS before or after new PC build is up and running?

Doing some last minute prep in-between prepping the office. Looking on MSI's site I see there is a new BIOS for the X570 Tomahawk WIFI motherboard. The date on the BIOS is Aug. 9th, 2021. This will be newer then the BIOS on my brand new X570 Tomahawk WIFI. Should I flash this new BIOS before I do anything else? I'm new to the Windows/PC environment so i don't want to get ahead of myself. Should I wait to upgrade this until after I get it up and running. I concerned with making too many changes without knowing what I'm doing. I've create the BIOS flash drive on my MAC. Reformatted to; ExFAT, master boot record. Renamed file to MSI.ROM I will rebuilding my first PC this Saturday after being a Mac guy for close to 35 years. Windows 10 64bit Pro I've watched a few videos that go over the process, just wanted to check to see if I should do it before I do anything else. I'd rather to just turn it on and have everything work before I start fiddling with anything, just not sure that's realistic. Thanks for the help,

:)

Brand new PC build - Windows 10 will not load - ACPI Bios Error

May I ask why you gave me a bad rating before I had the chance to reply to help you further?

Newer UEFI firmware doesn't have the AHCI setting because it is standard now as the SATA controller default.

If you tried everything in the list including re-enabling UEFI and turning off CSM to use the new features of the UEFI BIOS, what is the exact failure behavior now? Normally when someone does the troubleshooting steps, they report results to give us clues.
Normally when someone says they tried everything, they haven't really even read through the dozen or more steps. I say this as someone who has far more experience on the web troubleshooting install failure than anyone else.

Another step to try on new builds is to remove every component except what's absolutely required to install Windows.

But if you've completed every single step which resolve 90% of failures, then one thing you can try is to move the hard drive into another PC (alone) to install Windows 10 to it, then move it back to the target PC. Windows 10 is remarkably adaptive to new hardware
without needing adaptive restore. If it will start it will swap out all drivers requiring several restarts.

This will also tell us if the problem is with the install or the build. Then if necessary you can tear down the build and try over.
