Yes, but most of their boards don't have the most basic protections (like all of the DIY mobo industry), because their customers don't care at all. For example

Yes, but most of their boards don't have the most basic protections (like all of the DIY mobo industry), because their customers don't care at all. For example, on MSI PRO Z690-A, you are able to install coreboot to replace the official proprietary firmware from the OS, because the firmware regions are left writable. They have some signing in 700-series Intel boards like I have mentioned in another comment, but I can't tell how it actually works.
