i remove C9796 look bad, is it necessary?

LP8550 or the feedback trace to ball A5 on LP8550.

I remove LP8550 U9701 but C13 is missing TP_BKL_FAULT i don't see on schematic if this net is necessary.
Can you confirm if i put a new one, the missing pin is stopping the device from working?

Unused pin. Make sure to check ball A5 trace for continuity!
