Uploading new builds to steam should only upload the differences between the two builds making upload sizes pretty small, however, FMOD always counts as a new version even if it didn’t have any changes.

Are you finding the last modified date of any of the files in the FMOD integration are being updated between editor reopens? Particularly anything inside the “ **\Content\FMOD** ” directory. Otherwise if you are using source control, are you finding anything in the FMOD integration is repeatedly marked as changed?
