How to disable the entry of empty values being inserted into postmeta if not filled in?

There isn’t any way in ACF to prevent empty values from being inserted.

If you really don’t want the values in the database then you need to create an acf/save_post filter https://www.advancedcustomfields.com/resources/acfsave_post/, check all the values and use delete_post_meta() https://codex.wordpress.org/Function_Reference/delete_post_meta or another WP function for deleting the value from the database.
