I use a 512GB 960 Evo.  It's in an XPS 13 9350 rather than your system, but boot times are based almost entirely on storage performance rather than CPU or memory anyway, so this information should still be useful to you. Also note that the XPS 13 9360 runs its NVMe lanes in power-saving mode, which limits read performance to about 1.8 GB/s rather than the Evo 960's max of around 3.2 GB/s.  But even with that bottleneck, the time from the beginning of the spinning dot animation under the Dell logo (which is when the system starts reading from the drive rather than doing its own pre-boot checks) to the time I see the Windows 10 logon screen is about 3-4 seconds.  If your 7567 runs its NVMe lanes at full speed, your boot time should be even faster.

I will guess 10 to 15 seconds....  If you need me to be more precise, is this from a powered down state or a restart?

The Magician benchmark shows 2700 MB/s reads and 1800 MB/s writes.

I have x400 sandisk 128 m.2 and it starts in 15 seconds. It is a pity that no one has it in 7567 because I do not know if it makes sense to change.
