TPS65988DK: PD Firmware setting for optical fiber Thunderbolt3 cable.

Part Number: TPS65988DK

Dear experts,

We are building a TBT device and it's based on Gorilla Creek reference design. It can work normally when I used TBT passive cable.
When I used TBT3 optical fiber cable, it can't be detected TBT device. And there is no VBUS voltage output.

We have tried Intel reference board Gatkex creek by using TBT3 optical fiber cable and it can work normally.
But Gatkex creek's PD controller was maded by Cypress. I don't have Gorilla creek RVP to verify this function.
If I want TBT port can support optical fiber cable, which setting should I modify?
Here is our pjt setting: TPS65988DK_0504_Final.pjt
