I work with evaluation board STM32G474-EVAL1. Some peripherals are connected to Multi function expander (STM32L152CCT6) which is accessed via I2C. Where can I read the proticol specification?

Not exactly a protocol specification, but https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Drivers/BSP/Components/mfxstm32l152 should give you a picture.

The only way to work with MFX is to understand its source code? Thank you anyway...

It's not the MFX source code; it's the interface to MFX, i.e. this goes to the target (the 'G474) if it wants to use the MFX.
