Ideas on how to boot & install linux on a headless (broken screen) Laptop computer

asking for a friend: He has a UEFI laptop which he wants to install linux onto, the problem is that the integrated screen is broken, and as such he can't enter the bios, and change the boot priority to the linux USB installer. i had in mind of buying a RS-232 compatible adapter and plug it in a USB port, and try to control the bios from there, but i dont think the UEFI would display it's output in here, What could my friend do to access the UEFI interface without video output?
