Resolved! STM32F407 (STM32F427). Is it possible to configure PH1/OSC_OUT pin as GPIO when HSE BYPASS (external clock generator on PH0/OSC_IN pin) is enabled?

I need to feed STM32F427 with external clock generator and at the same time use PH1/OSC_OUT pin as GPIO output.What I doing.STM32CubeMX 6.3.0, FW_F4 v1.26.2 Firmware, "Pinout & Configuration" TAB -> Categories -> RCC -> High Speed Clock (HSE) BYPASS ...
