Can we change the pin in SPI for wireless connection?

Hello,

I have a Project on Arduino nano V3, i Need 4 PWM for Servo motors.

Normally we connect CE on pin 9, but i Need pin 9 for another Servo motor.

Can i Change the pin CE to D4 for example or SPI Need a PWM too? (a precise frequence)?
Because i already did that now i can not program the board (may be it's defect) not via Serial USB and not via ICSP too!!

CE can be another pin, make your software match it. SPI does not need it to be a PWM pin.

Thank you for your reply! I appreciate that

I just test Arduino Nano with nrf24l01, when i change CE from 9 to another PIN, it don't work!

I test it with Nrf24L01-Poor Man's 2.4 GHz Scanner:
