Setting up pi 400 without sight

Hello everyone! It’s been a minute since I posted here, but I have a question. I just purchased a pi 400 kit, with an extra 128 GB Micro SD card. I want to run Ubuntu mate on this, because that is what I’m running very successfully on my desktop and laptop. Is it possible to set this up without sighted assistance? I E.can you launch orca once you boot up the installer? Is there an installer? Never done this before, so any help would be greatly appreciated. Thanks much in advance.
