New Universal Login Text Prompt Changes in Template HTML

All, is there any way I can change the text prompts that appear on our new universal login template in the HTML itself?

I’m passing in a custom query parameter as indicated here and would like to change the text prompts on the page depending on the value of my query parameter.

Using the API in my case is not an option as these texts to need to change based on the parameter.

Can anyone assist on what my options are for this? Do I need to render a completely different page template or is there anyway to change the text prompts via Liquid?

is this possible or no?
