i2c at startup

Hi guys,

i really love this project.
i am using an instance of dietpi for my application using some i2c OLED display.
Is it possible to show some bootscreen animation on the display during boot process?
i was thinking about a systemd service which will kick in in the beginning and will be killed, when the real application gets started.
what is the earliest possible moment in systemd to talk to i2c devices? is there another way beside systemd?
