Why does hardhat-ganache try to start service when running scripts?

Question

I am coming from the truffle framework background where the deployment of scripts was straightforward, add the scripts in the migrate directory.

I want to test the deployment and learn about how transactions are created in the Ethereum chain. But seems like hardhat-ganache is trying to start the already running service. Is there any possibility to fix it?

Here I have provided the ganache service url and from account

networks: {
    ganache: {
      url: process.env.GANACHE_URL || 'http://localhost:7545',
      from: process.env.FROM_ACCOUNT
    },
