Yes, this is possible.
The easiest way would be to add a custom html element on a page or post. In it you can specify to add a iframe which shows LI.FI on your site: <iframe src="https://transferto.xyz/embed" width="500px" height="600px"></iframe>
More details on how to pre-configure the form you are showing can be found here:https://docs.li.fi/products/more-integration-options/li.fi-embeddable
