Can we use gpio16, gpio17 of esp32 pico module?

i found that it is used to connect the flash chip and it is not recommended. i am running out pins for my application so is there any way to use these pins.

At the moment, with esp-idf, you cannot do this. In the future, we do want to allow other SPI devices to run in parallel with the SPI flash, but this is only good for some specific use cases.
