This old post suggests that the cutoff for Arizona was 1360 last year: National Hispanic Recognition Program Class of 2021 - Specialty College Admissions Topics / Hispanic Students - College Confidential Forums - Admissions Discussions and Threads
I do not know if it is accurate, and even if it is, if that number is representative of what the cutoff might be this year.
