To get 25.10 Desktop ISOs with TPMFDE bits, we need matching pc-kernel
and snapd otherwise we get errors like so when running
`snap prepare-image`:
WARNING: the kernel for the specified UC20+ model does not carry
assertion max formats information, assuming possibly incorrectly the
kernel revision can use the same formats as snapd
error: snapd 2.68+ is not compatible with a kernel containing snapd
prior to 2.68
Use the "dangerous" model, which allows overriding the channel, and pick
up the matching pc-kernel which is not yet on 25.10/stable, where the
non-dangerous model would expect to find it.
