Should be easy enough. I ended up flashing my nrf52s from a programmer loaded onto an OG arduino clone I had lying around so that I could keep the nRF-DK board dedicated to running dev builds.

To give you an impression about how much trouble that was: I also bought a few dedicated general purpose programmer boards (cheap maker stuff), but in the end the arduino approach felt more accessible. Iirc the difference was that the purpose-built boards had more assumptions about what exactly they'd be used for baked into their documentation and I don't know enough about all that stuff to see through them
