Local install EN user here.
I first quit EN and restarted the MBP.
Moved my "accounts" folder (~34 GByte) to an external drive.
Went in Terminal to the Library folder where accounts resided and entered
ln -s <path to the moved accounts folder, e.g. /Volumes/SSD07/EN/accounts/> accounts
which creates the symlink.
Started EN, there was a dialogue window showing up very shortly telling that some user data gets migrated (?).
EN is fully functional and I saved some 30+ GByte on the local drive
