Hello, is there a way i can use the gpio 18,19 and 21 from the esp32 to connect a device from a project im trying to do? I think the pins i need are connected to the Ethernet chip.

there are 3 free gpios you can use. they have connect with ESP32 module's pin directly. see the photo. they are: GPIO32, GPIO33, GPIO14
