The power consumption document linked here off the CYW43907/CYW54907 Product Guide can be leveraged for both the CYW43907 and CYW54907.

You can check test.powersave or test.apps_sleep (43xxx_Wi-Fi/apps/test/apps_sleep) application inside SDK. Usage will be the same for 54907 as mentioned in the help document

There are different mechanisms for wifi and processor power saving. For example, look into PSM and PSM with high throughout APIs.
Using these APIs significantly reduce the energy consumption of the board.
Also note that the CYW board includes other stuff that consume power. Therefore you might not be able to reach a very low power consumption if that is what you are looking for.
