Can I become an RDN without a bachelor's in nutrition?

I'm in my senior year of my bachelor's in Neuroscience and looking into accredited master's programs for the RDN path. I plan to take a gap year after I graduate from my bachelor's to get clinical experience and complete possible graduate program prerequisites. I'm unfamiliar with some of the terminology in many grad school websites, so I have been having a hard time understanding whether I need a bachelor's in nutrition in addition to the master's. I would appreciate any clarification or guidance in the right direction 🙏
