i got bios updated to E7C02AMS.1H6 (CPUZ finds my MB as B450 TOMAHAWK (MS-7C02))
I did this to enable TPU2.0 and secure boot.
With that options enabled cant boot OS - UEFI mode cant see my drives.
With disabled can boot but cant enable secure boot option.
I found out that my virtualization support also went off - cant run any machines on my VMWare Workstation.

My question is which version of BIOS should I went back to to get back my graphical BIOS with full options accessible. instead of my current old like bios with accessible option cut to only limited set ??!!

If Your old disk have non UEFI GPT partition, then isn't possible to see any disk.
Problably must be iniciated with UEFI Mode with GPT mode.

Hello,
In order to enable TPM/Secure boot, the system must be set to full UEFI (in BIOS Boot Mode). If your system was previously installed as legacy, you won't be able to boot the OS. The OS needs to reinstalled from scratch.
I don't think the VM support was disabled permanently in any BIOS version.
Reminder: This is a polish forum, polish is a main language. We do speak english here, but if you want support/a chat about your problem in english - I would suggest using global/english version of our forum: https://forum-en.msi.com/index.php
I'm closing this topic.
