There is no option or parameter in URL to display the mobile view on desktop. Which code (HTML, css,js,....) is used depends on User Agent, so you must request your page with a mobile device to get the code and the view for this device (User Agent).

Again, as long as you have cache varies in .htaccess defined warmup with crawler will not work. The UA of the crawler is fix and doesn't match with cache varies in .htaccess.
Why should that work? If you enter a specific UA that doesn't change the UA of the crawler. The crawler's "name" is still the same, but it could work, if you remove all custom cache varies from .htaccess.
