I got final result from Icom tech support:

According to Icom, T2H model, specific in US market does not offer ANI
mode. They have tried T2H in their site and confirmed that ANI mode
is not available in T2H. Reason is unknown. They said it could be
some reasons that Icom disable ANI mode in those radio, and there are
no way to reverse that.
