Force "Request desktop version" on mobile

Short question: I would like to have "Request desktop version" always set to true on mobile. Is there any way to do that?

Detailed question: I'm working on a website which is looking good on desktop. I'm using wordpress with WPOcean theme and i'm building my pages with Elementor. So the website is fully responsive and life is beautiful.

However, for a specific page with a picture as a background, i can't obtain the desired design on a portait mode mobile.

Firstly, i tried to make a mobile specific page with a redirection. It works well, but this involves double work all the time i want to make a change on my page, and it would like to avoid this solution.

Enabling the "Request desktop version" solves my issue, it looks great with it. So i searched what was the code behind this, and investigated the related questions. It is always about changing the viewport meta like in this thread : How to force desktop view on mobile devices - Bootstrap?

However, it seems like requesting the desktop version does extra job based on the web browser, resulting in a better view. Am i right?

Thus, do you have an idea how to request this automatically on mobile accesses?

Thank you for your time!!
