Queries regarding sdmmc instances in agilex fpga

Hi,

I am using intel agilex fpga AGFB012R24B2I3E,for that fpga in hps pins and peripherals section for sdmmc only one instance is provided.My design has both emmc flash and sd card.How i connect both?.And i saw in one of the agilex evaluation board schematics both sd card and emmc is connected how i enable both if i have only one instance of sdmmc?I found it on AgileX F-Series FPGA Dev Kit

schematics document number is K57065-001-A.Kindly give an insight .

Please find the hps instance and evaluation schematics page with doubt on the attachments
