Reboot after screen lock

I’m new to linux
There is a laptop with 2 physical disks, 1 - for windows (entertainment / home), 2 - for fedora (work).

Everything works correctly, before loading I am offered a choice of system, if I did not choose, Fedora is loaded.

I disabled all sleep / hibernation / suspend modes in Windows and Fedora.

But there is 1 problem, when I block “super + L” laptop, after 5 minutes the system enters standby mode, then reboots and Windows boots. How to fix it? How to make sure that the lock does not enter into the reboot?
