After some research… Is there a way to check equivalent BTC-ETH address without any privkey risk?

No there is no way, Eth address are a partial hash keccak of the public key.

A lot of people already said that sharing the hash sha256 of the public is a secure way to prove tha you know the private key, and that is correct.

double Sha256 hash, I don't know how sure it would be against brute force, when giving the hash256 of the public key directly by mistake.

It is a single hash.

Bitcoin use a double hash to generare the address (sha256 - rmd160) that is the so called double hash.

With only the sha256 hash we has half of the way to the address without compromise the public key.
