Porting From STM32L432 to STM32L496: No USB Clock Enable/Disable Bit?

I am porting some code from the STM32L432 to the STML496. The STM32L432 had a macro that would allow you to stop the USB clock on APB1 (_HAL_RCC_USB_CLK_DISABLE), but the bit in the RPB1ENR1 register used to do this (RCC_APB1ENR1_USBFSEN) doesn't seem to have an equivalent on the STM32496. Is there an easy way for me to functionally recreate stopping the clock?

    Hello @jvara​ ,

    On L496 it becomes __HAL_RCC_USB_OTG_FS_CLK_DISABLE().
