HP Z620 works well with Win11 insider build

[Calaudude]

as my windows 10 boot drives was not uefi 
I had to convert it with

mbr2gpt /convert /allowfullos

reboot 

bios

I had just to enable uefi secure boot
activate uefi boot drives in bios

activate secure chip in bios TMP 1.2

reboot

anyway after restart everything was fine and win 11  update went through easy

incase you dont get on insider win11 update use that

I can confirm that I managed to install Microsoft Windows 11 Insider Build on my HP Z420 v2 (yet Intel Xeon E5-2680 v2 processor normally not accepted, just like TPM 1.2). I did not try with the original graphics card (Nvidia NVS300), having mounted my Geforce GTX 1050 TI.

So it proves that Microsoft is the one who imposes its "minimum" configuration, and that computer manufacturers will follow like sheep. And of course we'll say that it's Infineon who makes the TPM chips present on the Zx20... Well, that will always keep the industry going ! Sorry, but it pisses me off to no end.  😖

I just hope we can still do it with the commercial version of Windows 11 if no TPM 2.0 update is planned for the Zx20 !
