Can cudaMemcpy() use both pci and nvlink?

I am running the nvbandwidth test on a 8*A100 nvswitch server. My question is, when GP0 reads from GPU1 using cudaMemcpy() and P2P is enabled, can cudaMemcpy() use both the link of pci and nvlink? that is split data into two parts and transfer data via pcie and nvlink separately?
