I wish I could tell you the official home page of UEFI BIOS Updater (UBU), but I am not sure where it is. Decades ago, I used to trust some freeware, but these years I am more hesitant. I wish UBU was open source. 😦

This is not an open source tool. It is closed-source freeware, which works on Microsoft Windows systems. I’ve not used this, but I’ve heard of others who use and recommend it. If you are going to use it, please read all the documentation first, there are many caveats and warnings.
