would it be possible to connect a 1.8V Octal SPI Flash (like the Adesto ATX064P) via FlexSPI to a i.MX RT1020?

The schematic of the i.MX RT1020 EVK shows this possibility. NVCC_SD is switchable between 1.8V and 3.3V (see page 4).

But according to the reference manual, Table 83, Ports GPIO_SD_B1_xx are supplied by NVCC_GPIO which is 3.3V.
