I am a total noob in creating blockchains, and I am trying to make one using geth with PoA.

I want to make a PoA private blockchain where transactions and smart contracts ( usage and deployments ) are totally free ( i am not planning on using ether at all, and there will be just interaction with and between smart contracts in the blockchain ) .

Will setting --gasFee 0 on every node do the trick as seen in this question, since OPCODES transactions fee work with gas as well?

I've also seen this question with a suggested solution but there's no feedback.

If anyone has any ideas or suggestions on how to properly achieve, please explain as much as possible since I've said before, I'm a newbie.

I think it's very important to get familiar with geth Ethereum client first. https://geth.ethereum.org/docs/fundamentals/private-network#initializing-geth-database
