Hi GimpMaster,
To run config #1 on default board, please do

  1. ODMDATA = 0x90000
  2. Apply setting of xhci@3530000
phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>;
		phy-names = "utmi-0";

tegra186-quill-p3310-1000-c03-00-base.dts
tegra186-quill-p3310-1000-a00-plugin-manager.dtsi

  1. Disable usb2-std-A-port2 and usb3-std-A-port2
usb2-std-A-port2 {
				nvidia,lanes = "otg-1";
				nvidia,function = "xusb";
				nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
				nvidia,oc-pin = <1>;
                                status = "disabled";
			};
			usb3-std-A-port2 {
				nvidia,lanes = "usb3-1";
				nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
				nvidia,oc-pin = <1>;
                                status = "disabled";
			};

It should enable PEX1 and disable USB_SS0.
