Inspiron 3542 using Kubuntu 19.10 (Debian, Linux based OS).

From https://www.dell.com/support/article/en-uk/sln171755/update-the-dell-bios-in-a-linux-or-ubuntu-environment?lang=en , I am at least 4 updates behind, the version of BIOS I have is A01. I always put it off because it appeared to be a Windows only update and I only use Kubuntu/Linux. I have no need for Windows.

Do I have to do the BIOS update one by one, or simply do the latest ? In simple terms, does the latest include all updates ?
