   I wonder if the `to_hex` function will work for your usecase -- 
https://arrow.apache.org/datafusion/user-guide/sql/scalar_functions.html#to-hex
   
   ```
   ❯ select to_hex(123);
   +--------------------+
   | to_hex(Int64(123)) |
   +--------------------+
   | 7b                 |
   +--------------------+
   ```
