Error while checking for headers using :selenium web driver in rspec/capybara test

I have a rspec/capybara test which fails with the following error because Selenium does not support headers, however this test works fine with :rack_test driver. Since a lot of my other tests heavily rely on Selenium I caot change the driver to :rack_test.

How do I fix this? Is there a way to run this specific test with :rack_test driver while other tests still use the default :selenium driver?

 Capybara.configure do |c|

 end

    expect(page).to have_content('Stores:')

    # search page
    visit '/search'
    expect(page).to have_content('Search')
    click_button 'Search'

    sleep 5

    click_button 'Download CSV'
    expect(page.response_headers['Content-Type']).to eq('text/csv; charset=utf-8; header=present')
    # expect(page.response_headers['Content-Disposition']).to match('filename="transactions.csv"')
  end
