Hello
May I ask how I should configure the HAL file
For example, I want to use PE9~PE15 on stm32f407
How should I write it in the HAL file

When you have made your Ethercat device, follow examples from here https://github.com/linuxcnc-ethercat/linuxcnc-ethercat

Hello
Which pin on the MCU corresponds to the enc-pos-scale? Where can I find it

[MetalMusings]

That's not a pin on the MCU. It is an Ethercat pdo entry.
This is defined in in the ESI file, written to the eeprom and picked up by the lan9252.
The application code in the STM32 uses the pdo info to know where to to write the encoder position value.
For info on the pins, see the KiCad schematics and the C++ code.
