> Getting 50% load and peaks of 100% spikes.

What load do you mean here if not CPU ? ASIO load according to Cubase ?

> Network Adapter Disabled, Onboard Audio disabled, Wifi on airplane mode.

You can keep LAN adapter active, in case you want to browse someting in the internet.
But while recording I would not do this in parallel.
I would not enable WLAN, more likely to cause issues.

> DPC latency checker measuring

AFAIK DPC Latency checker is not suitable for measuring Windows 10.
Use only LatencyMon.
DPC routines reaching 210 us execution time are fully ok.
The LatencyMon results are ok.

> I'm trying create a template to record with DAW monitoring with 96khz and 64 buffer size.

Challenging for a system to operate at double speed with lowest ASIO buffersize, but theoretically not impossible.

Ok, here you seem to have the tool consuming much CPU ...

But besides a high ASIO (??) and higher CPU load that you mentioned ...
Do you have audio loss ?

Here my last Latency monitor stats

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts.
LatencyMon has been analyzing your system for  0:10:05  (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   360 MHz
Measured CPU speed:                                   9 MHz (approx.)

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs):   134,80
Average measured interrupt to process latency (µs):   1,780293

Highest measured interrupt to DPC latency (µs):       133,90
Average measured interrupt to DPC latency (µs):       0,646323

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
