Hi,

When removing just one ball from the footprint not much will change. There is probably some change in mechanical stability/toughness since there is fewer points of contact with the PCB but it should not have a huge impact unless the final product is to be used under extreme conditions where frequent stress and shocks to the device occurs.

For the J24 since it is just a GPIO or NFC pin it does not serve a critical function unless you wish to use NFC or that I/O pin. So removing it is probably fine. But i do want to say that we do offer design reviews here on Devzone, if you wish to all you have to do is create a new ticket here either privat or public depending on if you want to share your design openly or not. Then name it something like HW review nRF52833 and add the schematic(PDF) and layout files preferably in GERBER format.

Regards,
Jonathan
