Running mkfs.<type> [...] generates a File System and its UUID. any way to personalize it? In a fashion like "not generate UUID with numbers '4' and '5' or letters 'b' 'c' ".

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.
