From sheet 6 of the schematics: NanoPi R2S (NanoPi-R2S-V1.1-2009-Schematic.pdf): VCCIO4 (U12) = VDD_PHY_IO VCCIO6 (H6) = VCC_IO_33 NanoPi R2S Plus (NanoPi_R2S_Plus_2309_SCH.PDF): VCCIO4 (U12) = VCC_IO_33 VCCIO6 (H6) = VCC_18 rk3328-nanopi-r2.dtsi describes the R2S. On the R2S Plus this leaves the VCCIO4 domain configured for 1.8V while supplied with 3.3V, and the VCCIO6 domain, which carries the M.2 E-key SDIO signals, configured for 3.3V while supplied with 1.8V; the latter prevents the optional RTL8822CS Wi-Fi module from initialising at all. Describe the actual supplies. The vendor's own kernel uses the same values [1], although there they come from a .dtsi shared by the whole NanoPi R2 family, so the schematics above are the reference. Tested on an R2S Plus: Ethernet still links at 1Gbps and the SDIO Wi-Fi module enumerates.
