I have deployed a contract with basic mint and transfer of NFT. I did some transaction on that contract like minting into one address and then transferring the token from one address to another address. You can checkout the storage of contract address here. https://better-call.dev/ghostnet/KT1ExoT6i2EnVBHMdVDrfDeNX7bUHdKjJYzH/storage
Since I have already done transfer of tokens and it did work fine. Now I need to change the policy to policy = FA2.NoTransfer() and disable the transfer of tokens between the address. I guess it is not possible to update the contract in tezos , so what can be done here to disable the transfer of that NFT contract? Any suggestion would be appreciated.
