DM648 SPI Module SPICS1/2 can be set or clear in normal state not in communication progress?

Hello, can you help me?

1、DM648 SPI Module SPICS1/2 can be set or clear in normal state not in communication progress, in other words, I want to set or clear the SPICS1/2 like GPIO Pin, is it possible?

2、I have another problem after this question，thank you for your reply.

The GPIO mode for the SPI pins was not tested on DM648.  However, it worked fine for the GPIO mode on the DM648 EVM.  Since its not being tested, this feature will be "use at your own risk".
