If so, it needs to be configured as (HDMI + DP) Screen Config, and the default firmware is (HDMI or DP + Mipi) screen config.
In addition, you can use the default firmware to connect only the type C to HDMI interface screen to see if it is displayed? （That is, do not connect the first display HDMI, only connect the second tpye-c to HDMI display）

The only Firmware that work’s with one Display is the Android 9 Firmware made by mo.
There i can choose RGB 8bit and get the right colour, but only for the HDMI Port.

Maybe @mo123 can help you.
