Use ICSP and free up pin 11 ,12 and 13 on arduino nano ?

Hi..

I am playing around with a arduino nano.

First i had a sd card reader connected to SPI pins 11, 12 and 13.

Then i wanted to free up the pins 11, 12 and 13.

So i used the SPI mosi miso sck of the ICSP header.

But it seems the pins 11, 12 and 13 are now not free to be used for other things.

Is there a way to free up the pins 11, 12 and 13 for other use when you are using the SPI of the ICSP header ?

Thanks..

The ICSP pins and pins 11, 12 and 13 are electrically connected so there is no way to free them up if you want to use SPI. And, if you think about it, the Atmega 328 does not have any extra I/O pins.
