You don't have to use UEFI secure booting - most machines can fall back to legacy booting using BIOS settings. If you do that, you won't use any Microsoft signed code.
Back in 2017, Intel said that it was going to deprecate the “Legacy” CSM
by 2020. They might have changed their schedule but I suspect we’ll start seeing hardware without anything but UEFI.
I believe that is still Intel's plan.
However, as happens often, people are confusing UEFI and Secure Boot. UEFI is a replacement for the ages-old BIOS - Secure Boot is an extension to UEFI to create a "trusted" (for whatever that may mean) boot chain to get to the OS. You can have UEFI without having Secure Boot enabled (that's what I do on my systems).
Legacy BIOS has its own set of issues, like no GPT support, MBR disks are max 2TB.
