Raspberry Pi 4B CAN HAT support ?

B

I got a Raspberry Pi 4B with a RS485 CAN HAT.
FreeBSD 14.0-RELEASE is working perfectly fine but I am not able to see / interact with my CAN HAT.. Is there a need to add some special parameters ? (I already added the ones from the documentation) or CAN HAT is not supported by FreeBSD ?

Thanks
