You don't, it's basically impossible with this kind of setup and it was never something they designed for. The mission of NIF is to perform fusion experiments so that they can replace nuclear bomb testing. This whole talk about power generation is probably just marketing to get more funding.

It was pretty clear during the press conference. Everyone involved was talking about "stewardship" as the first part of their statements. There was some handwavey stuff about private actors taking this experiment and running with it for power generation, but it should be pretty clear what the market thinks about this technology by observing that fusion startups that claim to want to shoot things with lasers have almost no funding.
