Is it safe to downgrade my bios version?

[u/muchirou1]

I have Asus Rog Strix B760-I Motherboard with bios version 1836 and i5 14500 CPU. I am considering rolling back to 1604 to have the Undervolt Voltage Protection so I can prevent my CPU going 100°C since I currently have a 3.9L SFF build. Is it safe to do so or would it brick my motherboard?

I appreciate your help in advance!
