Regain your privacy! Adopt /e/ the unGoogled mobile OS and online servicesphone

I’m sorry, but this phone is not on the list of supported devices.
It won’t run /e/OS.

is it not possible in any way to install your operating system? or you can tell me if there is an alternative operating system, I don’t like android at all and inconvenient and I hate google
