It shows that your latest bios update was on 2/3/2021, you might installed the wrong bios version, you should download the latest one which is the 7C52v3D version on your motherboard website https://www.msi.com/Motherboard/B450M-A-PRO-MAX/support
Make sure you download the second one and not the beta, cause the beta version might have some problems. Here's a video on how to update your bios

i updated to the latest versions 7C52v3D TPM is enabled but still i cannot switch to uefi i think the bios does not recognize my gpu "MSI GTX 1050 TI"
in gpuz you can see my gpu is uefi ready .
in the setting i switch from csm to uefi save and reboot but it goes back to csm even if my HD is GPT , i have one other hard drive mbr in but just data .

edit: i cannot save any settings in the bios not even boot order it goes back to default after every reboot the time and date stay the same maybe its the battery i will change it

I CANNOT ACCESS M -FLAH ASWELL I JUST UPDATE THE BIOS WITH SVET TOOL !

Your 1050 Ti might need this firmware update: https://www.nvidia.com/en-us/drivers/nv-uefi-update-x64/

Also, yes, change your CMOS battery. If that is empty, no settings will be saved when the PC is turned off.

Make sure you download the second one and not the beta, cause the beta version might have some problems.
No, i would recommend the beta BIOS, because the AGESA 1.2.0.6c is an important microcode update for the CPU. The AGESA 1.2.0.5 microcode (or what MSI call "AMD ComboAm4v2PI") used in the previous BIOS is problematic, see here. Don't let the "beta" tag unsettle you, it's just because they wanted to get this out as soon as possible. Other brands also released it as a beta.

Can you also list you build see posting guide >>Posting Guide<<
And definitely up date to the Beta BIOS or roll back to AMI BIOS 7C52v3C 1.2.0.2 as 1.2.0.5 seems to broken in more ways than original suspected.
