OP - you're paranoid
, so I want to chime in here to keep you from over thinking. General rule of thumb - if it's working, don't break it.
First, you have a good motherboard that will make you happy a long time. In all fairness to Microsoft, they have radically improved their driver support and source pool. Now, I am not a fan of Microsoft, I'm just speaking from 25 years of consulting. It used to be that their drivers were hit/miss and mostly
horrible. The fact of the matter is that many of the various pieces of hardware you will use with your new build all use the same chipsets. It really isn't an issue anymore with one exception.
Graphics cards - yes, get those drivers from the maker.
Another note: it is possible to brick your system updating your BIOS. For me, and I have 45 years in the industry, I need a critical reason to do this. In fact, with all of the laptops I've bought, and systems I have built, I have updated the BIOS one time.
The only issue I have with your build is Windows 11. That OS is the
worst I have ever seen. As near as I can tell, it's Windows 10 with advertising hooks. These updates Microsoft pushes out typically have nothing to do with security. The updates almost always change your default settings, turn back on backups to the cloud, attempt to sign you up for services, download copilot, and on and on and on. I told you I wasn't a Microsoft fan-boy. I still get angry with their automatic forced reboots.
