If CAN0 FD is enabled, are all CAN channels not allowed to use Rx FIFO?

[chengsz12060]

My board is MCU S32K144.
I need to use two channels CAN.
CAN0→CAN-FD
CAN1→CAN Classical
CAN2→not used

Question1：
Is it allowed to use CAN1's Rx FIFO when CAN1 (CAN Classical) receives data?

Question2：
If CAN0 FD is enabled, are all CAN channels not allowed to use Rx FIFO?
