If you want to measure power consumption of nRF52840 then just do not run NimBLE on it. If you want to measure power consumption of nRF52840 running full NimBLE stack (I assume controller+host) then OS is just one of the components of overall power consumption. Make sure that you do not have unnecessary stuff enabled in your build (so there are no unused peripherals enabled) and use app which works like a regular product (so e.g. does not have console where all debug output is printed) and you will get pretty much accurate results.
