Excuse me, that was my fault! I read over what you did. You have unlocked exactly one I2C EEPROM available on the Rock Pi.
# Set "on" to enable the optional hardware interfaces while set "off" to disable.
intfc:pwm0=off
intfc:pwm1=off
intfc:uart2=off
intfc:uart4=off
intfc:spi1=off
intfc:spi2=off
intfc:i2c2=off
intfc:i2c6=off
intfc:i2c7=on
# Devicetree Overlay Enable, uncomment to enable .dtbo under /boot/overlays/.
# EEPROM on I2C2
#intfc:dtoverlay=at24c02
I did not touch the EEPROM for my test, but changed the off in the line with “intfc:i2c7=off” to an on.
