Windows 11 Pro, my PC will wake itself back up when sleeping & start itself back up when shut down

This issue started about a year ago.  It's annoying, as I am currently living offgrid and need to conserve power to my battery backups easily.

I have tried replacing the GPU and the CPU.  I have tried adjusting the power saving settings, but I don't know of any settings that are supposed to have this effect anyways aside from waking up for network, and it does this even if starlink is unplugged.

Please help me go through troubleshooting steps.
