Making text fonts high res in a low res pixel art game

Question

Hi! I am making a pixel art game in a 640x360 resolution for integer scaling. I noticed that of course text fonts are rendered at this resolution but with canvas_item stretch mode instead of viewport the fonts are rendered in high quality even if they are rendered at 640x360, is there a way to render parts of the ui like the fonts with a separate stretch mode?

Thank you for your time!
