CAN Klipper reserved pin problem EBB36v1.2 / Manta E3EZ #39

I have the problem that some of the specified pins are already reserved for CAN. This means that I cannot use the ADXL cs_pin: EBBCan:PB12. Klipper gives error, is reserved for CAN. The E3EZ uses PB12 and PB13 for CAN communication. I also cannot use the heater_pin: EBBCan:PB13, also reserved for CAN. So can I not use CAN in this board combination? I shortly had the idea of using the unused EXP port, pin PC2 and PC3, but I'm missing the R120 there. I had hoped to have an improvement with this board, but in retrospect the purchase was a bad decision, even for the EBB36v1.2.
