Acer nitro an16-41 device bios is corrupted

[Serwintes]

I have a RTX 4070 laptop with Ryzen 7 7840hs processor, ZGU motherboard. I opened the hidden bios settings with the FN + TAB keys. I did some tinkering and went into amd overclocking. From there I changed the pstate0 freq value from 3800 to 4000. I didn't touch the voltage part. I clicked save and exit. When the device restarted there was no image anymore. I can't enter the bios. I put the cmos battery in and out but it didn't work. Do I need to perform a bios recovery to go back? I did some research and found my bios file ZGUr.fd. I put the file to a Fat32 8gb flash drive. I plugged in the USB memory stick and plugged in the charging adapter. I started the computer by pressing the Fn + Esc keys. The USB light started to flash, but it did not fix even though it continued like this for 20 minutes. Probably the bios file name is wrong. What must be the name of this file? Sorry for my bad english.

My bios file:
