[Request] Completely updated BIOS for Asrock Z68 Extreme4 GEN3



Hello, guys!
Please advise me!
I have Asrock Z68 Extreme4 Gen3 motherboard with i7-2700k cpu and I want to update bios to 2.31A version from post #6.
I has already created fat32 partition on one of my hdd drives and instant flash list this file like possible update.
When I switch pc on I can see these versions of sw/hw:
"Version 2.02.1205. Copyright (c) 2010 American Megatrends, Inc.
The current version of Intel ME firmware is 7.1.10.1065, backup is 7.1.10.1065.
Z68 Extreme4 Gen3 UEFI P1.10"
In UEFI BIOS:
"Microcode update 206A7/14"

Is it okay to update to 2.31A from version UEFI P1.10?
And after first boot I should load default uefi settings and save it, right?
Thank you very much!

p.s. by updating I want achieve:
a) possibility of boot up from nvme ssd (currently boot up process looks like UEFI=>grub on sata ssd => boot with root partition on nvme ssd) which is installed through pciexpress 4x adapter.
b) more overclocking/stability and power(voltage) control
c) usb3.0 stability (there was too many magic with that in the past)
d) may be video gpu compatibility and at all gpu perfomance

And again, thanks for the minute of your time!
With best regards, A.
