Bios update question (Function keys behavior)

My laptop is Acer Aspire A315-42 (Ryzen 4700U 8+256GB)
My function keys F1-F12 doesn't work unless I press them while holding the Fn key. I want to use F1-F12 without holding the Fn key. After some research, I found out that I have to update my BIOS (ver 1.05) then go into the BIOS to change it. 

I found 5 BIOS updates in https://www.acer.com/ac/en/CA/content/support-product/8050?b=1&pn=NX.HF9AA.012, should I install all five updates in order? or should I just go for the latest?

Also, I changed the default 2x4GB RAM kit to a 2x8GB RAM kit, will it have any negative impact on my BIOS update?

    Nope, just go for the last one.

    BIOS upgrades are different from normal updates in the sense that they don't go to the hard drive but to a ROM chip in the motherboard. Writing in there requires the chip to first be erased which is why it is sometimes called "re-programming" instead of updating. I'm of the opinion that they don't carry as much risk as they used to do years ago, there are safeguards in place and they're quite stingy.

    For example, by default you won't be able to flash an update that is older than the one you have. You will also not be able to flash if your battery is missing, or has less than 25% of energy. Not that flashing requires an insane amount of time, it's actually rather quick, but they tend to go conservative with these things.

    Another safeguard are digital signatures, the BIOS upgrader won't do anything if there upgrade file is corrupted or not properly signed, and it requires the machine to be connected to the power adapter just in case.

    So update away, and change the setting from Media keys to Function keys ;)

    Also, I changed the default 2x4GB RAM kit to a 2x8GB RAM kit, will it have any negative impact on my BIOS update?

     No problem at all in that regard either.

    The latest update should include all the previous updates. BIOS updates always carry risks of adverse side effects or worse. Jack E/NJ

    Try going back to where you were before the RAM upgrade. then upgrade the Bios again, Where did you get the /ram from with the 2X4GB installed download from www.crucia.com their scanner it will tell you what upgrades are available for your RAM.
