Hi @rs-renato, may be sudo chflags nouappnd /etc/hosts on your host will help?

Or another solution could be:

sudo chmod -N /etc/hosts                    # Remove ACLs from file
sudo chflags nouchg /etc/hosts              # Clear the user immutable flag from file
sudo chflags norestricted /etc/hosts        # Remove the SIP protection from file
sudo xattr -d com.apple.rootless /etc/hosts # Remove SIP protection from file

But I don't have a Mac. Use these commands at your own risk, these are not tested.
