According to the Agilex™ 7 Device Family Pin Connection Guidelines, the 3A bank power supply and VCCIO_PIO_SDM should be connected together.
However, due to a problem in Quartus® Prime Pro Edition Software Power and Thermal Calculator (PTC) tool, the Report page displays the voltage of the 3A bank correctly, but the voltage of VCCIO_PIO_SDM does not match it.
You should follow the Agilex™ 7 Device Family Pin Connection Guidelines for your board design in accordance with your specific conditions/requirements.
VCCIO_PIO_SDM is a sense pin, and the current drawn by it is negligible in the report. This misreport does not noticeably affect the overall PTC calculations and thus can be ignored.
