Disable Sorting?

It appears to me that you are not attempting to edit the metadata in the ID3 tags of your audio files.  Music Mode and Podcast Mode rely on carefully curated ID3 tags.  I have never come across any way to turn off the automatic database processing every time the player detects new audio & deleted audio files. I guess it takes less than one minute ??

Have you ever tried using FOLDER Mode to access your audio file in your internal memory and external micro SD card?

 Here is a link to the Clip Jam User Manual

      (There is a very brief mention of Folders on page 5.)

You should be aware of a complexity using FOLDER Mode on the Clip Jam (and Clip Sport).

         Folder Mode does not provide any internal sorting of files.

                 The file order displayed is a direct result of the chronological order you load the folders and files from your PC.

         Maybe check out this webpage for a detailed explanation of “FAT” sorting problems in Folder Mode.
