I'm gonna close this as DNS names are intentionally lowercased in netbox:

3675ad2539/netbox/ipam/models/ip.py (L873-L874)

From a very short googling, it seems like DNS names are case insensitive. If we were to change this behavior your would need to create a feature request instead, but you would have to provide a very good reason for why it should be changed, as it seems to be a very niche case to want case sensitive DNS names.

My best advice is to create a custom field on the IPAddress model for your case sensitive DNS records.
