It's easy, just put the bios file on a pendrive, first make sure that the pendrive is recognized, although if it doesn't work, it's not a problem because you wouldn't be able to update.

Here you have a video of an Asus, it's the same since in Asus it's called EZ flash and in MSI I think it's M flash but it works the same.
You download the Bios file from its page and unzip it on a Pendrive, you enter the UEFI to M flash, select the pendrive and the bios file and click update, it will tell you that you can't turn off the computer or cut the power while it updates.
