i designed it using 1-bit sdmmc connection mode and the cs pin is not required.

OH I understand now. And when using sdmmc mode these three sdio pull up resistors are also a must? Beside SPI mode three resistors is not needed.

yes you're right you can read idf documentation for details how to work with sdcard with sdmmc mode and sdspi mode
