(SOLVED EXPLANATIONM BELOW)

I have the Problem that I did a fresh install of Windows 10 pro (twice) and enabled Secure Boot as well as fTPM (amd) to be Win 11 ready, but Windows still says that it doesn't recognize a tpm module. I installed the ryzen chipset drivers (because under Device Manager it said: "pci encryption/decryption controller") and under Security devices it only says: "AMD PSP 11.0".

Under System Information it says that Secure Boot State is : On

PCR7 Configuration: Binding Not Possible

Device Encryption Support: "Reasons for failed automatic device encryption: TPM is not usable, PCR7 binding is not supported, Hardware Security Test Interface failed and device is not Modern Standby, Un-allowed DMA capable bus/device(s) detected, TPM is not usable."

I'm loosing my marbles trying to just install Win 11 ffs..........! Pleas help meeee

My PC:

Mainboard: NZXT N7 B550 (Newest BIOS Ver)

CPU: Ryzen 9 5900x

RAM: 32GB 3200Mhz

GPU: RTX 3090

OS: Windows 10 pro

EXPLANATION:

Okay so as I found no real answer I started to look into another Problem that I had, my USB devices were on even after I turned the PC off. Turns out that the same setting that fixed this also fixed my PCR7 binding Problem as well as the tpm problem. I had to go to ACPI Configuration settings and change the Deep Sleep settings to "S4 and S5 enabled".
