Mediatek has been making phone SoCs since forever now, they have two lines - Helios and Dimensity. They’re used in many phones, usually on the lower end. Even Samsung uses them. Both lines have abysmal custom rom support compared to Snapdragon phones, so I don’t think you can hope for much there.
A DE has little to do with this, it’s a driver, it gets loaded when you plug in a compatible device, there’s no interaction. This should have been disabled 2 years ago when the gaping security holes were found, and actually Greg had attempted to have it disabled in 2022 but it kept getting pushed back.
