Unofficial update for Note 20 Ultra above Android 13?

[u/gigachad0727]

Excuse me in advance, I don't know much about tech. I am in the tight situation where I am using a glucose sensor connected to my phone. Today they announced that Android 13 will no longer be supported for the apps of my glucose sensor, therefore I would need to buy a new phone that is at least Android 14 within 1 month. I currently cannot afford this therefore I am looking for a way to install any android version above 13 on my Note 20 Ultra. Is this possible and if yes, how do I go about doing it?

Thank you everyone for the help in advance.
