Locking bios chip?

I am using the Asus z590-p mb that comes with 2 bios chips and was looking for a method to turn on flash protection for them both.
The 2 chips arent backup and main one scenario rather the bios content is divided between the 2 ( according to the manual it says 128 MB flash rom+ 64 MB AMI bios)
is there a tool or software i can use to enable this feature ?
