How do I prevent Windows Error Reporting from deleting my live kernel dump file?

I have a system (Windows 10, version 20H2, OS Build 19042.1052) that locks up regularly for a few minutes. It doesn't crash/blue screen, but a live kernel dump is logged in the Application event log:

Windows Error Reporting event id 1001:

I would like to view the PoW32kWatchdog-20210615-0615.dmp file in WinDbg.exe so I can see the stack trace of the faulting thread. However, the .dmp file is nowhere to be found:

C:\WINDOWS\LiveKernelReports\ -> the file is no longer there, presumably because Windows Error Reporting attached it to its report C:\ProgramData\Microsoft\Windows\WER\ReportQueue\Kernel_1a1_b56071bcde394c864256bb672ce88048e33283f_00000000_cab_23199732-b72b-44e5-b26f-f179c6892d31 -> does no longer exist, presumably because the report has been sent to Microsoft before I am able to access it C:\ProgramData\Microsoft\Windows\WER\ReportArchive\Kernel_1a1_b56071bcde394c864256bb672ce88048e33283f_00000000_cab_23199732-b72b-44e5-b26f-f179c6892d31 -> I find a report.wer file here, but it is an name-value-pair file of a few kb, not the .dmp file I'm looking for.

How do I prevent Windows Error Reporting from deleting the .dmp file? Or is there another way to make a copy / backup of the .dmp file before it is deleted by Windows Error Reporting?
