install.py not enabling I2C

[imaplt]

When running the command: sudo python3 install.py from the online user guide, the I2C is not being enabled. You must first enable it using raspi-config. You can see the error when doing the status using: sudo systemctl status spc.service
It will tell you that it cannot find I2C in dev. Once you use raspi-config to enable it it will then give you the correct status.
I have been able to duplicate this twice on fresh installs.

Update: It looks like the config.txt file has moved. Here is the message you get when you try to look at the original as indicated by your documentation:
imaplt@raspberrypi5:~ $ cat /boot/config.txt
DO NOT EDIT THIS FILE

The file you are looking for has moved to /boot/firmware/config.txt
