STM32F412: Changing CAN bus BAUD rate on the fly

I have configured CAN module 1 on the STM32F412 and it works fine when initialized with a certain BAUD rate (For example 500K). I have a GPIO input, which when toggled needs to changed the BAUD rate to 250K. The sequence I am following with STM32Cube...

STM32F412 - CAN bus disable filter configuration.

I got the CAN bus on the STM32F412 with STM32Cube_FW_F4_V1.25.2 - up and running but I have noticed that the Initialization configuration requires the filter to be enabled and configured properly. If the filter is not configured and enabled, the CAN...
