Problem with BIOS settings reverting back to original

Hello. Nice to meet you.

I am using a GPD MicroPC and I have a problem that I cannot solve, so I need your help.

I am using a GPD MicroPC to shoot VR videos, and I have been using it with BIOS settings changed, but when I recharge the battery and turn it on again after the internal battery is completely dead after not using it for a while, the BIOS settings that I have set revert to the original settings. Is there any way to avoid this?
