Has she looked at what Honors entails ? It’s not the same at all schools but many students batch them all together. My son applied to some, but not others based on offerings.
At some schools, Pitt for one, you can take the classes without being in Honors.
Please be cognizant of not just ‘Honors’ but what it means for that school.
If it’s that important, then how about a different school where they might get into a program ?
Good luck with UMN.
