There may be some confusion between the Hispanic Scholarship Fund, which is need-based, and NHRP, which is a designation like NM.
There are some older discussions in the Hispanic Students forum http://talk.collegeconfidential.com/hispanic-students/. As far as I know, the biggest automatic merit scholarship for NHRP is U Kentucky https://www.uky.edu/financialaid/scholarship-incoming-freshmen though it pays to hunt around.
