If you’ve got the material/compost/manure, just pile it up on the beds you want to have as no-dig.
In an ideal world but if your soil is home to tough perennial 'weeds' such as couch grass , horsetail, bindweed etc it doesn't always work and often requires years of patience by which time people can become a bit disillusioned with the idea.
Mind you rotavating land riddled with perennial 'weeds' just cuts them up and spreads them around.
I’m no expert. In the link I provided, Charles Dowding specifically mentions how to deal with things like couch grass. The only thing I’ve had to do more often since going ND is get the hoe out, but that’s little and often, just the very surface.
