i.MX8M mini ENET IO voltage

As per i.MX8M Mini Datasheet NVCC_ENET supports 1.8V/2.5V/3.3V IO voltage.According to Ethernet PHY (AR8031) used in i.MX8M Mini EVK board, MDC,MDIO are 3.3V only tolerant and  in EVK ENET IO (NVCC_ENET) voltage is set to 1.8V (used Voltage Translators for MDC,MDIO pins).


Is there any limitation or issue when we set ENET IO(NVCC_ENET) voltage  to 3.3V ?


We want to set  NVCC_ENET to 3.3V to avoid Voltage Translator on MDC,MDIO pins with the same Ethernet PHY in our Custom design using i.MX8M Mini &  Nano CPU.
