Upscaling workflow

Hi guys,

I am a newbie here and possibly overthinking this. I have generated AI images with midjourney and upscaled creatively. The sizes I download are 1824x2592. I am using Canva to design the posters. I am aiming to make A0 sizes first. Taking the upscaled image to upscayl x5 creates a file that is 9120x12960. I believe that results in a dpi of 275 for the A0 size poster I am making. How would I ensure that after upscayl I can hit the magic 300dpi? Hope that makes sense!
