Steps to reproduce

If src has security.secureboot=true, performing incus copy src dst -c security.secureboot=false will not update the OVMF_VARS file, making the VM unbootable.

After copy:

-rw-r--r-- 1 root  root      540672 Feb 16 21:07 OVMF_VARS.4MB.ms.fd
lrwxrwxrwx 1 root  root          19 Feb 16 21:07 qemu.nvram -> OVMF_VARS.4MB.ms.fd

If then performing incus config set security.secureboot=true followed by incus config set security.secureboot=false, then the files will be updated:

-rw-r--r-- 1 root  root      540672 Feb 17 11:52 OVMF_VARS.4MB.fd
lrwxrwxrwx 1 root  root          16 Feb 17 11:52 qemu.nvram -> OVMF_VARS.4MB.fd
