Enable the HDMI 4K port located next to the USB Type-C power port. It's driven by DP0 on the RK3588S via a RA620 DP to HDMI converter. Note that ROCKCHIP_VOP2_EP_DP0 is defined as 10 in dt-binding header, but it will trigger a dtc warning like "graph node unit address error, expected "a"" if we use it directly after endpoint, so we use "a" instead here.
