Queries related to GPIO functionality

Hello, We are planning to use the ESP-32 chip for a project. I had a few queries regarding the pinouts. 1. For our hardware we are not using any PSRAM. So can we use pins GPIO 16 and 17 as general i/o pins? 2. We are using an external flash GD25Q32CTIGR. Can we use the pins gpio 9 and gpio10 as gene...
