How to Enable I2C on AML-A311D-CC

technically, yes, since it’s a dtb overlay

just download the wiring-tools repo [1], build the dtbo file (just type: make, need dtc tool installed first - can do this step either in x86 host environment or in Alta board)

then enable it use “ldto enable i2c-2”, similar as this post AML-S905X-CC (Le Potato) 480x320 ILI9486 3.5" SPI Touchscreen Display

you might want to explicitly tell ldto as following:
export VENDOR=libre-computer
export BOARD=aml-a311d-cc
