Cube gives warning to enable non-existent setting on U575 project

When compiling code for the U575 from the IOC file a warning pops up that SMPS must be enabled.  However, we cannot find this setting under the PWR tab nor via the A-Z listing of properties.  What must be done to clear this warning?

    Hello @marrob @Eqqman 

    Sorry for my late replay. To enable SMPS on the STM32U575ZIT6Q using the Pinout & Configuration menu on the .ioc file of your project, you have to go to Power and Thermal -> PWR -> Low Power -> check the Case Power saving mode -> on the Power Saving tab under Configuration, change the Power Regulator from LDO to SMPS. for the Pop-up message, you can ignore it clicking on the yes button of the Message. It is just a warning to have better configurations. You can't disable it but you are not obliged to follow it.

    Hello @Eqqman 

    Can you add more details (which MCU are you using exactly and which CubeMX version).

    Best Regards.
