Hi QD Thanks for your request. If the new device you going to use required a GND connection, then you will need to modify the board. If it is the other way round, i.e. the new device required a NC, then you shall be fine: https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/solutions/rd03132006_933.html Thanks.
