PCIE_DIS signal in EM9190

The EM9190 product technical specification defines a PCIE_DIS signal that allows selecting the host interface type (unconnected/low for PCIe, high for USB). Given that the default is PCIe, does this mean the EM9190 cannot be used with the USB host interface on already existing hardware platforms where the corresponding pin is currently unused? E.g. is it that a system that already supported EM7455 modules will not be able to use EM9190 modules due to the wrong PCIE_DIS signal input?
