Hi Akash,
it depends on many details. If you can manage to make a very small gap between
GND and VBUS, then this might already give enough capacitace to allow the SS
signal to cross the slots.

Subject: [SI-LIST] Caps for signals changing reference layer
Hey Folks,
I am designing a board for USB3 SS and with my current stackup, I will have SS
signals changing reference from GND to VBUS for a small portion (near another
connector).
Can I get away with it or should I used decoupling caps near the crossing, how
do I calculated the caps value?
I don't have any space for more than two caps near the connector. Any
suggestions?

Thanks
Aakash
