you mean no GUI non non-free backports yes or
no GUI, but non-free yes and backports yes?

    > But, with a minimal install with GUI, non-free and backports enable, there is a dependancy problem when fai install non-free package (linux-image-amd64: Depends linux-image-5.6.0-0.bpo.2-amd64 [...] but it is not going to be installed) 

Strange. I can see that non linux-image pacakge is in your mirror.
I'll dig deeper into this.

In the past, we did not had backports for the nonfree firmware
packages for buster. They are now available and I can adjust the
fai.me configs.

Sometimes we have dependency problems in fai.me if a newer kernel package
is available, but linux-image-amd64 still have a dependency on an older
version.
