You can easily do that with a custom scalar.
For example using the graphql-scalars library:

import { asNexusMethod } from '@nexus/schema'
import { JSONObjectResolver } from 'graphql-scalars'

export const JSONObject = asNexusMethod(JSONObjectResolver, 'json')

That assumes you import all types in you nexus config.
If you want to have a backing type for an input, then you can also add something like this to your config (not tested):
yarn add type-fest

typegenAutoConfig: {
    backingTypeMap: {
      JSONObject: 'types.JsonObject',
    },
    sources: [
      {
        alias: 'types',
        source: 'type-fest',
      },
    ]
}
