Direct access to I2C/SPI/CanBus from CM4

Dear all,
I’m going to run some python code on Raspberry side and need to access some peripheral hardware directly from this code running on RPI.

I’ve found that RPI CM4 connected to Base Board using UART
“CM4 UART(GPIO14–TXD , GPIO15–RXD , GPIO16–CTS , GPIO17–RTS) is connect to Tel2 on the CM4 Base.”

Could you please suggest any feasible way how to connect HW to CM4 GPIO ports or how to forward board’s interfaces like TELEM1, TELEM3 or CAN1, I2C to Raspberry ?

Thank you in advance
