Does STM32H735G-DK board support CAN FD?

Hello, I'd like to inquire if the STM32H735G-DK supports a CAN FD transceiver, or if I should purchase an external transceiver

Hello,

No need to add external tarnceivers:

From the board's schematics you have three CAN interfaces on the board each one having its own transceiver:

From the board's UM2679 :

So read carefully the "limitation" section.

Just one more thing: be careful where you connect it, these are non-isolated interfaces.
