Now cypress supports passing user agent in the header for cy.visit as well as cy.request:

it('Verify Social Sharing Meta Tags', () => {

      'user-agent': 'LinkedInBot/1.0 (compatible; Mozilla/5.0; Apache-HttpClient +http://www.linkedin.com)',
    }
  });

  cy.document().get('head meta[name="og:type"]')
    .should('have.attr', 'content', 'website');
});
