"Bricking your partition"
What partition are you referring to? The OS installation partition? Pray tell how a bios overwrite could affect your "partition"

You are changing your system's basic settings while it's running, if it's a bad BIOS it can crash and take down the OS partition. If you update the BIOS from within the BIOS the OS cannot be affected.

You cannot do this type of update/roll back from within the bios (change from UEFI back to BIOS), hence needing to use the utility.
You are changing the bios while its running, regardless of what method you choose.
I don't agree that a bad bios upgrade can affect your OS installation - worst case in my view is that you wreck the bios.
It's not about the BIOS running, it's about the OS running. The OS isn't running while you update your BIOS from within the BIOS.
I doubt that you aren't able to do that type of an update/roll back from the BIOS. That would mean that you have no chance of recovery if you aren't able to boot anymore because of a bricked BIOS.

Well you cannot change from UEFI back to bios using the built in Q-flash utility.
I don't understand why you think that the boot partition has anything to do with the bios, because it doesn't.
These motherboards also have "dual bios" so if you brick one, its not a problem as you can boot using the second bios, then rewrite the first from the backup.
The OS hasn't got anything to do with the BIOS, but if you update to a bad BIOS from within the OS and that BIOS causes the PC to crash you might brick your OS. It's like pulling the power plug, most of the times you will be fine but it's still not a good way to shut down your PC. Updating to a bad BIOS can happen quite often, so why take the risk by updating it with the OS running.
There are other ways of updating the BIOS than the onboard utility, lots of cheaper mainboards don't even have a feature like that. Doesn't mean you have to put your main OS in danger.

I am well aware of that, hence also suggesting the bootable USB option.
What you speak of is a tiny risk and very very unlikely (cant remember the last time i saw a hard power off cause an issue with an OS, very rare these days), but ok, and even smaller risk that you would brick the bios and break the OS simultaneously. Ive been using and building PCs for about 20 years and working in IT for 14 years, I have never seen a bios update break an OS installation.
I once broke my OS when we had a power outtage, since then i don't do stuff that can cause a sudden shutdown i cannot control anymore. The rig was from 2005 i think.

Actually a running sytem does not acces the bios / uefi in any way. It's job is to start the system gather information on hardware and settings find a boot medium and boot to an os. By then the os gets full control over the system.
That's basically why you have to reboot after an in os uefi/bios update. If you break it down, the risk that your system crashes is lower, if you use an usb stick or other boot medium. Leaving basically only a power outage as risk factor. If you do an in os update there are more risk factors, that could lead to a botched update and bricking your board. But that can't damage your os install. And if you get a new board, unless it's the same model, you should do a reinstall anyways.

I've updated BIOS's within the OS.. its just exaggerated how bad it is. Just let the thing do what it needs to do and restart.. boom. Though MSI's live update software makes it more easy to do so.
