SN65DSI86: Is it necessary to read EDID for SN65DSI86 communication

Hi

The customer has an EDP screen, adjust the timing sequence and porch value according to requirements, and the screen cannot be lit.

When asked by screen manufacturers, they say their screens are protected and do not support reading EDID.

SN65DSI86, there is a description of reading EDID,

I want to confirm whether the communication of SN65DSI86 needs to read EDID?Will not be able to read EDID lead to abnormal communication,

Can I communicate without reading EDID?How to configure the register.
