Hello, is there any way to use EXTI simultaneously in different ports with the same pin number?
Examples for MCU STM32L071CB:
Using PA4 and PB4, or
Using PA10 and PB10, or
Using PA6 and PB6, and so on

No, there is not. For a given pin number, only one port can have an active EXTI at a time.
This is a hardware limitation, see SYSCFG_EXTICRx for the underlying hardware limitation.
