How to get rid of accent?

I speak both English and Italian, with English being the primary language I speak to my Google Home/Gemini in. (Italians is set as a 2nd language in my Voice Match.) Recently, I had family over and asked it to "Gime me and explanation, in Italian, on xyz topic" and it did so. However, the Italian it spoke had a terrible English/American accent.

I asked it to redo it without the accent, only for it to tell me that as an AI generated voice, she doesnt speak with accents like a human would.🙃 Any suggestions on how to remove the accent when asking it to answer queries in the secondary set language?
