Delay Chip select line STM32U5 OSPI

I am using the NUCLEO-U575ZI-Q.

I am using the OSPI peripheral in QSPI mode.

The device I am communicating with needs a longer delay after the CS line is asserted low.

I have tried setting the "ChipSelectHighTime" to 8, but I think this only affects the "number of clocks which the chip select must remain high between commands." I do not believe this controls the timing of a delay after the CS is asserted. 

I also looked into the "Delay Block"; however, this looks like it controls delays for reads only if I understand it correctly.

How long of a delay?

Could you drive the pin as a GPIO manually around HAL_OSPI interactions?
