How to manual control the E-Tile transceiver's CDR mode of agilex 7

Hi, 

   fpga chip : AGFB014R24B2E3VNL

  Issue : rx_set_locktodat and rx_set_locktoref doesn't present in E-Tile's Transceiver's CDR, and I didn't found the related avalon register to control this part in the E-Tile Transceiver PHY user guide

   Does E-Tile  transceiver support this feature in Agilex 7 Device? If so, could you please share this part information?

Best Regards,

Lambert
