capture a xperf trace of the CPU usage. First Install the WPT which is part of the Windows 10 SDK. Now open a cmd.exe as admin and run this command to capture 30s of the CPU usage:

xperf -on latency -stackwalk profile -buffersize 2048 -MaxFile 2048 -FileMode Circular && timeout 30 && xperf -d C:\HighCPUUsage.etl

Open the trace in WPA.exe, load the debug symbols from the Microsoft symbol server.

Now Drag & drop the CPU usage (Sampled) graph to the right side of WPA and choice this layout and extand the stack of the SYSTEM Process and look where the CPU usage splits:

enter image description here
(in this demo, the Kernel is busy zeroing the RAM).

Now you should see the cause. If you need help, share the compressed ETL file so that I can take a look at it.
