Does adding a password to BIOS prevent malware from infecting it?

Does adding a password to BIOS prevent malware from infecting it?

I'm looking into ways of hardening a computer's security. One of the things is the BIOS.

Does adding a password to the BIOS prevent malware from infecting it?

I have seen this article: Protecting the BIOS from malware but it doesn't mention about passwords.

Any information on this is greatly appreciated.
