Do the newest computers still have ROM?

Now that many computers use UEFI instead of BIOS to boot the computer, and UEFI instructions are usually stored in a hidden hard disk partition, does this mean the newest computers do not need to have ROM, which is used to store BIOS program in the old days? Or, was ROM unnecessary long ago even before UEFI existed, as BIOS program and settings were stored in flash memory (so as to store the changes in settings by user)?
