I want to design custom board for nrf52840. I will be using configuration 5 from Reference Circuit nrf52840. I do not want to use NFC can I leave NFC pins not connected. For antenna design can I use the antenna design in nrf52840 DK?

1. The DK comes with a debugger / programmer already https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/if_mcu.html
2. Take a look at this: https://infocenter.nordicsemi.com/topic/nwp_027/WP/nwp_027/intro.html
I am reading product specifications for nrf52840. In section 5.3.8.2 Regulator specifications, REG0 stage. The max current reading of 25 mA are at which voltage level of High voltage mode because high voltage mode can be from 2.5 V to 5.5 V
