lgpio.error: 'GPIO busy'

[jayofelony]

I have waveshare V2 e-paper and when I run the python test file I get an error:

pi@jayofelony:~/e-Paper/RaspberryPi_JetsonNano/python/examples $ python3 epd_2in13_V2_test.py 
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Apparently this has to do with the latest raspios Bookworm release. GPIO pins 8 and 17 are already being used.

[jayofelony]

in /boot/firmware/config.txt add the following dtoverlay=spi0-0cs and it should work.

Please tell me which line exactly to add?

I can't get the 4WD Smart Car Kit for Raspberry Pi to run. I have a Raspberry Pi5. I post the error that he writes below.
