How can I change firmware from tianocore to seabios?

Hey. I’m looking for way how do I change the default firmware in LXD from tianocore to seabios. Personally, I don’t like UEFI.

You can’t. LXD is designed around the use of a modern machine type and the use of edk2/uefi.

Maybe you can trick LXD into starting with another firmware using raw.qemu but this wouldn’t let you boot any of our images nor would it be a supported setup.
