It's not a good idea to load a settings profile you saved with one BIOS version on a different BIOS version. You should only load a settings profile on the same BIOS version where you saved it.
That said, if you want to ignore this warning, you can still do it. You have to save your profile on a USB stick as a file. There should be an option for that somewhere in the BIOS menus. You can't just save your profiles normally, all those things saved on a motherboard chip will be wiped when you update your BIOS, that's why it has to be in a file on a USB stick.
What you should really do is, you should take out your phone and take photos of the different BIOS screens, then use those to get your overclocking settings back manually after the update.
