will this work with msi pro z790?

It tells you what models it works with. Otherwise, I would not recommend it. Also, understand if you are buying this for W11, it is the TPM in your processor which you need, not this TPM Module.

Does this TPM work on the MSI B550 Tomahawk motherboard?

Yes, this TPM module supports MSI AMD 500 Series Motherboards, which includes the MSI B550 Tomahawk motherboard.
