I know there is command that can change password , but are there also remove password and make wallet status as no password?

Run bitcoind or bitcoin-qt -server. You can control it via the command-line bitcoin-cli utility or by HTTP JSON-RPC commands.

You must create a bitcoin.conf configuration file setting an rpcuser and rpcpassword; see Running Bitcoin for details.
