For some reason it is well hidden, but it works for me.

I don't know about thru customization, I couldn't find any API calls. But
if you open your part in Inventor, go to the parameter table, then RMB on
the Equation cell for a parameter that is exported, a menu will appear that
has "Custom Property Format". Click the button and a custom property format
dialog will appear, allowing you to control the format of the parameter.
