Workers request.cf.region for italian regions doesn't fit ISO:3166

I’m trying to match the list of regional names coming from localization but I’ve found at least a discrepancy.

‘Lazio’, region of Rome, is found as ‘Latium’ in your service.
There’s no reference to ‘Latium’ on the ISO webpage:
https://www.iso.org/obp/ui/#iso:code:3166:IT

This is the list I’m using at the moment, but I’m not sure all names are right:

Basilicata
Calabria
Campania
Emilia-Romagna
Friuli-Venezia Giulia
Latium
Liguria
Lombardy
Marche
Molise
Piedmont
Apulia
Sardinia
Sicily
Tuscany
Trentino-Alto Adige/Südtirol
Umbria
Aosta Valley
Veneto

There’s no way for me to VPN all 21 regions to make sure request.cf.region gives a value a can match by string.
It can take pretty long to find people to log for me…

Any recommendation please?
