How to suppress the license expiration notification?

Hello all 

There used to be an evironment variable to suppress the license expiration notification from 30 to something like 3 days. 

CADCENTRE_LICENSE_FILE_WARN_COUNTDOWN=3 

Since this is no longer working is there some other way of suppressing that notification for Aveva Marine SP5 ?

The notification is preventing background scripts from executing (navisworks file generation etc).
