The system logs and printf are two different things over here. In your project sdkconfig file check if the parameter 'CONFIG_CONSOLE_UART_DEFAULT' is set.

This defines where all your console outputs are dumped into.

In your case you want to disable all the printf logs, you can try setting 'CONFIG_CONSOLE_UART_NONE=y'.

If you are doing it thourgh make menuconfig of esp-idf, it will come under - component config > ESP32-Specific > UART for console output (Default: UART0, TX=GPIO1, RX=GPIO3) > None

Hope I answered to your question. :)
