          man mkfs:



             -U UUID
          Set the universally unique identifier (UUID) of the filesystem
          to UUID. The format of the UUID is a series of hex digits sepa‐
          rated by hyphens, like this:
          "c1b9d5a2-f162-11cf-9ece-0020afc76f16". The UUID parameter may
          also be one of the following:

          clear clear the filesystem UUID

          random generate a new randomly-generated UUID

          time generate a new time-based UUID

          • There is no mkfs. There are mkfs.<type>. Each of them on its own may or may not support -U and the option may or may not mean what you wrote. E.g. compare what man mkfs.ntfs says about -U.
