How to declare types for Cypress custom commands under typescript-eslint/no-namespace?

Cypress documentation shows how to declare custom command types:

declare global {
  namespace Cypress {
    interface Chainable {
      /**
       * Custom command to select DOM element by data-cy attribute.
       * @example cy.dataCy('greeting')
       */
      dataCy(value: string): Chainable<Element>
    }
  }
}

But Typescript ESLint is unhappy about this due to "ES2015 module syntax is preferred over custom TypeScript modules and namespaces @typescript-eslint/no-namespace". Is it possible to rewrite this to import/export and if so, how? Or should I just disable the rule for this case?
