There is the following schematic in datasheet.

Becase there are pull-up registors with HDP line.(red circle)

Thank you for your reply.
I understood the role of registors.
I want to disconnect these registors.
Becase, Soc detected always HPD.
Is there any problem?
In reply to Masaaki Sugiyama68:
Thank you for your kindly support.
I understood it.
My system is the following figure.
When the PCB board is not provided Power, Source side always detects HPD high.
So, I want to remove the 1K-ohm pull-up registor.
