You may give trace API function a secondary optional argument, which specifies the options for this specific call. The possible options are:
disableStorage: BOOL. Setting this to true will disable storage capture (default = false).
disableMemory: BOOL. Setting this to true will disable memory capture (default = false).
disableStack: BOOL. Setting this to true will disable stack capture (default = false).
txHash: string. Setting this value will trace only the specified transaction.
