This video discusses making a FreeDOS Bootable USB using Rufus (Windows) or Unetbootin (Ubuntu) and using it to perform a UEFI BIOS from a Bootable USB. A FreeDOS Bootable USB is needed for Dell Models that have a SMBIOS of 2.6-2.9 (for example the Dell OptiPlex 390/790-3020/7020 and the Latitude E Series). A separate video is available for the OptiPlex 3040/7040 and newer models which can update the UEFI BIOS within the UEFI BIOS setup directly from USB.

The line of code to for Unetbootin to launch correctly is: sudo QT_X11_NO_MITSHM=1 unetbootin (should not be needed in Ubuntu 20.04 which addresses the issue)
