Crystals electrical capacitance (pF)

I need to replace the crystals with RK3399 and AP6398S, tell me what electrical capacitance (pF) is used by default?

Hello, The schematic for the Edge is here. Edge-V or Edge related devices are here, also has PCB drawings to help ID component locations.

In these documents, there is no such information.

12 to 22pF will work OK; 18pF is used by default.
