Those are the only configurable pins. The rest are required per the espressif docs

Thank you for sharing what you did find out. But:
Obviously the modified Waveshare schematic does not match with the modification on the photo: If you remove one 33R resistor and move another one to a different place, only one resistor can be missing in the schematic. But in yours, both R11 and R12 are missing. So, what function has the moved resisitor, and where is his place in the modified schematic?
This is not working for me,
I am using a Cisco switch and do wounder if maybe the auto negotiation could be an issue. I cannot ping the device at all.
this solution like put a 33Ohm resistor between gpio 17 and xtal1/clkin
yes bro these 3 pins are just for configuration esp32 with home assistance esphome
and must connect all pins without NC so the system works well
wiring guide
ESP32 | NC | 22 | 19 | 21 | 26 | 25 | 27 | 17 | 23 | 18 | GND | 3V3
LAN8720 | NC | TX1 | TX0 | TX_EN | RX1 | RX0 | CRS | nINT/REFCLK | MDC | MDIO | GND | VCC
I have the same switch Cisco POE and I hope everything with you is working well
me is working but not professionally. every press for the switch in switches need page alone to refresh the need to press again then run if you have any idea about this issue tell me
