Acer Predator Helios Neo 16 BIOS issue

i recently updated the bios from v1.13 to v1.18 in my laptop and then i read alot about the performance issues and the ram tuning in this bios version. And, i have noticed that the noise of the fan when its on high speed it's different to what it used to be in v1.13. So, is there anyway i can downgrade my bios version? Chatgpt is telling me to make a freedos bootable pendrive and flash the bios from the dos but its not showing the boot menu. So, what should i do?
