[En-Nut-Discussion] EIR: SD-Card on SPI

I developed a board and a firmware based on the EIR and Nut/OS 4.10.3. 
For I have no audio-codec-IC I would use the SPI for the SD-Card to get 
a faster data transfer. I read the workaround with the SSC 
(http://www.ethernut.de/en/hardware/eir/spi.html) but an upgrade to 
Nut/OS 5 isn't possible at the moment.
Can I change the OS in the configurator that the hardware SPI is used 
for the MMC or do I have to change the driver in code?

Best regards,
